The Megalithic Burial Tombs of Ireland

The people of Neolithic Ireland created magnificent burial tombs: the passage tomb, the court tomb, the portal tomb, and the wedge tomb. Each of these tombs indicates carefully planned and constructed architectural designs. The megalithic tombs provide many types of archaeological evidence such as tools, human remains, pottery shards, and other artifacts. Excavations of the megalithic burial tombs present archaeological evidence that gives insight into Neolithic Irish societies and religious rituals.
            The Neolithic Era occurred between the Mesolithic Era and the Bronze Age, sometime between 10,000 BCE and 2,000 BCE. The Neolithic Era is also referred to as the New Stone Age. The Neolithic Era brought with it changes in the way man lived, worked, and participated in society. The Neolithic people began as farmers, raising livestock, building settlements, and using tools.
            The changes that occurred in the lives of the people in Neolithic Ireland created a chain reaction. John Waddell in The Prehistoric Archaeology of Ireland added that farmers may have immigrated into Ireland and brought with them plant and animal species, as well as tomb building rituals.[1] These tombs became some of the most prominent Neolithic structures found across Ireland and other parts of Europe. The structures are known as megaliths and provide insight into the lives of the Neolithic people.
            Megaliths were created with large standing stones and some of these individual stones that make up a megalithic structure weigh several tons to a hundred tons. There are several different types of megalithic monuments; some of the most magnificent are the burial tombs. Sean O Nuallain in The Megalithic Tombs of Ireland explained that there are approximately 1,200 megalithic tombs in Ireland that are categorized into four groups: the passage tomb, court tomb, portal tomb, and wedge tomb.[2] Each tomb provides unique archaeological evidence and architecture.
            Passage tombs contain some of the largest groupings of tombs, also referred to as cemeteries. Passages are often decorated with geometric artwork carved into stones both inside and on the outside structure of the megaliths. Sean O Nuallain pointed out that the shapes may be shaped like eyes as a representation of people.[3] The tomb art may provide insight into Neolithic burial rituals, but the purpose is unknown.
            The passage tombs are often situated on the top of cleared hills. John Waddell described the architectural characteristics of a passage tomb:
            A typical Irish passage tomb consists of a chamber approached by a passage, both covered by a characteristic circular mound. The mounds may be built of earth or stone or          a mixture of both and they usually have a curb [sic] or retaining base….Passages are             narrow and built of upright (orthostats) and roofed in whole or in part with flat slabs (lintels); on occasion passages are divided into segments by one or more low transverse     slabs set on edge in the floor (sill stones).[4]

            Perhaps, the structures were built for seasonal, or calendar, ritual practices since the structures often face in certain directions. The tomb at Newgrange, in County Meath, faces the east and could indicate that it was constructed for calendar rituals. Waddell believed that on the morning sun on the midwinter solstice would shine into the roof-box and light up the chamber; previously it may have aligned to shine on some of the geometric artwork.[5] The significance of the architectural design and any ritual practice is unknown.
            Excavations of the passage tombs give many pieces of archaeological evidence. Radiocarbon dating of the artifacts and human remains yield different results at different locations and give the estimated time of construction and use between the late fifth and late third millennium BCE. Paola Arosio and Diego Meozzi in Stones of Ireland confirmed that evidence during a 1935 CE excavation, at a tomb in Carrowkeel in County Sling, contained a chalk ball, pottery, arrowheads, scrapers, and an axe head.[6] The evidence from other locations consists of a variety of objects such as cremated remains, bones, and personal mementos.
            The evidence discovered at several different passage tombs provide an insight into the possible ritual uses of the tombs. The depositions of chalk balls indicate that the tombs may have been used for other purposes, including fertility rituals.[7] Waddell commented that there may have been a pattern to how the human remains were treated during the funerary process; adults were more often cremated, while the bones of children often remained intact.[8] The evidence of animal bones at Fourknocks, in County Meath, may also suggest that burial feasts may have occurred at some location.[9]
             The archaeological evidence found provide clues that imply that the passage tomb builders came from settled communities. Nuallain claimed that the presence of wheat and pollen suggested that the land around Carrowkeel may have been cleared and use as farm land.[10] The presence of grains would indicate that if the land had been cleared and agriculture was a means of producing food that the farmers most likely remained settled in the immediate area. The evidence the burial feast also suggests that the animal were domesticated, which supports the idea of a settled community for stock breeding.
            There is an opposing view point to the theory of the settled Neolithic community. Waddell wrote that Goran Burenhult, a prehistory author, believed that the evidence of seafood located farther inland and the lack of pottery at certain sites supports the theory of a hunter-gatherer society.[11] Radiocarbon dating suggested that the passage tombs began in the late fifth millennium. Therefore, it is possible that the passage tomb builders had originally been a hunter-gatherer society and later developed into an agricultural society as it progressed towards the second millennium. The passage tomb cemeteries would also support this theory by indicating that new funerary rituals were continuously performed in these locations.
            Court tombs, similarly to the passage tomb, are some of the larger more elaborately constructed megalithic burial tombs and are often situated on hilltops. There are estimates that suggest that there are over three hundred court tombs in Ireland. Julian Thomas in the article Monuments from the Inside emphasized that the elaborate construction of the court tomb may indicate a division and stronger focus on ritualized practices, than on other activities outside of the tombs.[12] The court tombs have not withstood the effects of time as well as the passage tombs, and evidence is often difficult to find.
            The court tombs are also some of the largest megalithic tombs constructed. The construction of the court tombs contains many distinct features. Waddell acknowledged, “the characteristic features in the ceremonial courtyard, set in front of a gallery [burial vault] which is divided by jabs [stone side pieces] into two or more chambers….Courts vary considerably in shape: completely enclosed forms of oval or circular outline, are dominate in western coastal districts while U-shaped or more shallow courts are normal elsewhere.”[13]  These sites provide archaeological evidence of ritual practice and clues about the social structure of the builders.
            The excavations of several court tombs provide pieces of information about the court tomb builders. The evidence discovered has been of material goods more so than of human remains. Nuallain wrote that objects such as arrowheads, javelin heads, scrapers, axes, knives, and polished stone have been identified.[14] Radiocarbon dating, from pieces of archaeological evidence at various locations dates, places the construction and use of the court burial tombs between the mid fourth millennium to the end of the second millennium BCE.
            Several pieces of archaeological evidence provide details into different forms of funerary rituals. These forms of funerary rituals include cremation, burial, and mass graves. Jim Dempsey in Megaliths reported that at the court tomb in Ballymacaldrack, in County Antrim, and an excavation showed that cremation occurred in the tomb as well as the deposition of the bones.[15] Information provided at other locations suggests different funerary rituals were performed.
            Evidence present at the Creggandevesky court tomb, in County Tyrone, gave an indication of both mass burial and funerary ritual. Waddell suggested that there is proof that twenty-one people were cremated and that bone fragments suggest they were possibly crushed after being scorched during a ritual.[16] Waddell also wrote that Humphrey Chase believed that the some of the pottery fragments may have been used as part of magic fertility rituals.[17] The evidence available produces more than just clues into the ritual practices of the megalith builders.
            Like the passage tomb builders, the court tomb builders were most likely agricultural farming communities. Animal bones and evidence of grain in pottery may indicate a settled community just as in the case of the passage tombs.[18]  The location of the tomb on the hilltops also supports the idea of land clearing, similar to that of the passage tomb. All of these point to the theory of a settled farming community within the immediate area of the court tombs. The court tombs, however, may have provided more than just a funerary purpose.
            The location of the court tombs and the elaborate skill it had taken to build these megaliths indicate more than a ritual for funerary purposes. T. C. Darvill in Court Cairns, Passage Graves and Social Changes in Ireland insisted that the court tomb builders may have even participated in certain trades such as creating weapons with flint, producing pottery and a focus on building megalithic structures.[19] It is possible that these court tombs may have not only served as the community political and economic center as well.[20] The theory of the court tombs being used as a location for other religious rites such as the magic fertility rituals and evidence of many sharp objects, that would have been used as tools, help to support the idea of its use as a market. These suggest a cultural change and advancement in other techniques.
            The portal tombs were not constructed like the court and passage tombs. They are also often located in valleys, as opposed to along the tops or sides of hills like the court and passage tombs. Waddell observed that the locations of the portal tombs may indicate that they were placed in valleys and wooded areas because of the proximity to wood and visible protection.[21] Wood, however, was not used in the construction of the portal tomb, as it had been in certain cases with the court tombs’ roofing.
            The portal tomb’s construction was no easy feat for its builders to undertake. The builders have used man and animal power as well as leverage or a pulley system in order to stand or lift some of the heavier stone. Sean O Nuallain noted the characteristics of the portal tomb:
            In such tombs, a pair of tall, well matched jambs flans the entrance and between these is   often a door stone which frequently achieves full closure…. Poised above the entrance is        the heaver end of the single great roof stone which usually covers the chamber. …   Especially massive roof stones are characteristic. The roof stone slopes downwards from        the entrance and rests on a low back stone.[22]

            The objects found during excavations at different sites provide more insight into the funerary rituals than at any other megalithic tomb. At the portal tomb known as Poulnabrone, in County Clare, evidence suggests that elaborate rituals were performed. Colm Moriarty in Poulnabrone Tomb argued that the flesh was first removed and the bones were later place in the portal tombs after having gone through a purification ritual with the use of fire.[23] This theory implies that the process was lengthier than immediate.
            Poulnabrone produces other archaeological evidence that indicates possible violence between members of the portal tomb community members or skirmishes with other Neolithic communities. According to Waddell a piece of flint was found embedded in a hip bone and a skull was discovered with two fractures cause by aggressive blows.[24] Aggression or sign of skirmishes could have been the result of harder times for the portal tomb builders. Analysis of the bones that had been deposited in the site suggests more physical labor, malnutrition, and infections.[25] Radiocarbon dating provides information that the portal tombs were built and used between the early fourth and late second millennium BCE.
            The last of the Neolithic Era tombs to be constructed were the wedge tombs. Radio carbon dating suggests that the tombs were constructed and used between the early third to late first millennium BCE. The location of the wedge tomb is not unlike the passage and court tombs tombs and is usually situated on farm lands and hills. William Gerrard Ryan in A Survey of Monuments of Archaeology and Historical Interest in the Barony of Bunratty Lower, Co. Clare agreed that the wedge tombs are often found on the hills of fertile and well drained farmlands.[26] The features of a wedge tomb are difficult to mistake, because of the large stones used during construction.
            The wedge tomb was named for its distinct wedge shape. Nuallain described that, “the chambers form a long, relatively narrow gallery which decreases in height and width from front to rear. The front consistently faces in a general southwesterly direction….The roof is formed of slabs laid directly on the chamber orthostats.”[27] The wedge tomb was most likely constructed in a similar way to that of the portal tomb, through a series of leverage and pulley systems as well as with the strength of man and animals. The wedge tombs were also likely constructed for calendar ritual practices.
            Some of the wedge tombs were constructed similar to the other tomb types. The structures, especially two in County Cork, face in a southwest direction. It is possible that the structure was constructed to be face the sunset during the Gaelic harvest festival known as Samhain.[28] This may indicate that the tombs were constructed for more than just funerary rites, but also in calendar festivals or rituals making them religious centers.
            The wedge tomb builders were able to construct more goods as a result of the use of metals during the early Bronze Age. This cultural change allowed the tomb builder communities to create more elaborate products.  According to Paola Arosio and Diego Meozzi a gold necklace, called the Gleninsheen Collar was discovered in 1932 near the Gleninsheen wedge tomb, in County Clare.[29] Other wedge tomb locations have provided evidence of advanced trades with such as the Beaker ware pottery and tanged and barbed arrowheads.[30] These changes indicate advancement in metallurgy and technology.
         
   The use of cremations continued also with as the primary funerary practice by the wedge tomb builders. A few new objects were included in the rituals as the wedge tomb culture advanced. Waddell explained that better constructed and decorated pottery was created were discovered.[31] The evidence provided indicates a decrease in human remains and an increase in personal items, which may suggest that the items were deposited as offerings at the wedge tombs.
            There are multiple opinions on the exact purpose of the megalithic tombs, other than for funerary rituals. There are also many theories as to what the archaeological evidence suggests about the religious and cultural practices of the megalithic tomb builders. Waddell gave one more speculation as to the purpose of burial tombs; he believed that the megalithic monuments could have also been a way to signify territorial boundaries or land ownership of farmlands in the same way a person today would build a home or other structure on a property that they own.[32] The megalithic structures and archaeological evidence only provide pieces of a puzzle that may never be solved.
            The four distinct forms of megalithic burial tombs have provided evidence to suggest that the people of the Neolithic Era in Ireland had changed in several ways. The tombs began as places primarily for funerary ritual in the early Neolithic Era. The Neolithic culture progressed as it approached the Bronze Age and with it came changes to the architectural design of the megalithic tombs and their uses. The megalithic tombs may have been used for other religious rituals as well as for social and economic purposes.
            The locations of the megalithic tombs indicate what type of societies had constructed them. It is suggested the builders of the passage tomb may have originally been a hunter-gatherer society that eventually settled in the area of the megaliths and developed a society based on agriculture. The three other tomb types were constructed by mainly agricultural societies due to land clearing and the presence of grains. It is possible, however, that the builders of the wedge tomb may have focused primarily on livestock as opposed to planting crops.[33]
            The Neolithic builders created four megalithic tombs: the passage tomb, the court tomb, the portal tomb, and the wedge tomb. The builders created these tombs for funerary rituals, but the sites may have had many other religious and cultural purposes. Excavations of the different sites provided many archaeological artifacts. Studying the megalithic architecture and the archaeological evidence indicates that the tombs were of religious, cultural, and economic importance throughout the time of the Irish Neolithic societies.

Centralia, Pennsylvania Mine Fire: Past and Present

Note from the Author: In April 2020, the closed portion of Route 61(aka Graffiti Highway) in Centralia was covered in dirt. The owners of the property decided to take this step after continuous ATV accidents, injuries, fires, and vandalism rose significantly during the COVID-19 pandemic shutdown.

            Centralia, Pennsylvania is located in Columbia County, in the east central portion of Pennsylvania. Centralia was a town built around the coal industry, until a fire started in an underground mine. Today, Centralia is home to only several people, an important location for recent history, and has a haunting appeal to tourists. The most important lesson to learn from Centralia is how simple negligence can have a devastating effect on a community and the environment.
            Since the beginning of the 1900s Centralia has had a somber history. The town faced devastating effects of fires, the Spanish influenza, and the scandalous activities of the Irish organization called the Molly Maguires. According to Deryl B. Johnson in Images of America: Centralia, one of the worst plane crashes to take place before 1950 also occurred just outside of Centralia.[1] Joan Quigley in Pictures: Centralia Mine Fire, at 50, Still Burns with Meaning noted that Centralia is most famously known for its underground mine fire, which is considered to be the worst mine fire in the United States.[2]
            Centralia was once a booming coal town, incorporated in the 1840s, that grew into a large community. Jon Guss in Inferno: The Centralia Mine Fire suggested that Centralia’s peak population was in the 1890s, with an estimated population over 2,500 before its decline.[3] The town was filled with homes, businesses, churches, and bars, until one fateful day in 1962 when events took place that drastically changed the town forever. A mine fire began in the Mammoth Vein of anthracite coal and it is estimated that it could continue to burn for a thousand years.[4]
            There are many speculations as to what caused the fire in Centralia, but there is one theory that is widely acknowledged. The fire sparked during an annual trash burning on Memorial Day weekend due to human error. Robert H. Nelson in Devastation by Degrees stated that a coal company left garbage burning over an abandoned mine shaft.[5] No immediate action was taken to put out the fire, because of the inability to predict the rate of speed of the spreading fire and finances for the project to put it out.[6]
            Greater attempts to extinguish the underground fire were not taken, until it had become a health and safety concern. A. T. McPhee in Fire Down Below reported that the fire could not only cause carbon monoxide poisoning, but also ground cave ins.[7] In 1981, media attention was drawn to the town when a twelve-year-old boy was rescued after he fell into a pit caused by a cave in.[8] The fire only continued to expand.
            The townspeople and government officials tried to come up with solutions to avoid the growing hazardous situation. According to Johnson by 1984 approximately seven million dollars was spent on efforts to stop the fire.[9] The fire only continued to extend into more seams. The resulting agreement was a forty-two million dollar buy out, giving families the money to start somewhere new.[10] Not everyone chose to leave the town, many decided to remain in their homes.
            Over the years more people have abandoned the town and more structures were demolished. Centralia, once home to thousands of people, became a ghost town. Only a few houses and residents remain in the town. The streets that were once lined with structures remain, but where the structures once stood wilderness has found its new home.
            Since the 1980s, Centralia has been removed from most state and national maps. There have been many discussions about trying to put out the fire to reclaim the mines. Several residents remained in their homes and fought against eminent domain.[11] In October 2013, approximately eight remaining residents won a court battle and were legally able to remain in the homes.[12] They fought to protect the homes that they hold dear, despite any health concerns.
            Centralia has become the center of attention for people both domestically and internationally. Many books and articles have been written about the town’s history. Centralia is often highlighted on websites featuring top abandoned towns and scariest places. Centralia has helped to peak creativity for artists, photographers, musicians, and writers. The town was even used as inspiration for the movie adaptation of the video game Silent Hill.[13]
            Today, Centralia is a hotspot for parties, off-roading, tourists, and those who like scenic walks. Cars and tour buses are often seen pulled off on one of the abandoned roads. Many people stop to take in the sights, remember Centralia’s history, or to observe the land ravaged by fire. There are signs posted by different government agencies warning of the dangers of walking on the land.
            One of the popular spots for tourists to walk is down the closed section of State Route 61, where the highway’s asphalt has shifted and buckled from the heat below. Visitors walk around the portion of the cemetery that remains. Others hike up the hill that overlooks the town where you can view road grids of the former town. The air smells of sulfur and steam raises from vents and cracks on the surface.    
            Each season in Centralia has its own haunting beauty. During winter, snow sits atop birch trees and blackened logs as the warmed ground remains damp. Spring brings rains that create a creepy feel as an abundance of steam raises from the dampened ground. During summer, the surroundings come alive with beautiful green plant life. Autumn brings mountains full of beautiful colored trees that surround the barren former town.
            To many people Centralia is a place of sadness and memories of what once was. To others the former town is a place of inspiration and has a strange magnificence. Either way, Centralia will be remembered for its past, and the effects of a continuing underground fire. The fascination with the mine fire will always beckon people who are curious enough to venture into the area despite the dangers. One question remains, how long will it be before the government takes control of the fire and reclaims the mine?
