The Coffin Stone, also known as the Coffin and the Table Stone, is a large sarsen stone at the foot of Blue Bell Hill near Aylesford in the south-eastern English county of Kent. Now lying horizontally, the stone probably once stood upright nearby. Various archaeologists have argued that the stone was part of a now-destroyed chambered long barrow constructed in the fourth millennium BCE, during Britain's Early Neolithic period. If a chambered long barrow did indeed previously exist on the site, it would have been built by pastoralist communities shortly after the introduction of agriculture to Britain from continental Europe. Long-barrow building was an architectural tradition widespread across Neolithic Europe. It consisted of various localized regional variants; one of these was in the vicinity of the River Medway, examples of which are now known as the Medway Megaliths. The Coffin Stone lies on the eastern side of the river, not far from the chambered long barrows of Little Kit's Coty House, Kit's Coty House, and the (now destroyed) Smythe's Megalith. Three other examples, the Coldrum Long Barrow, Addington Long Barrow, and Chestnuts Long Barrow, remain on the western side of the river. The Coffin Stone is a rectangular slab lying flat that measures in length, in breadth, and about in width. Two smaller stones lie nearby and another large slab is now located atop it. In the 1830s it was reported that local farmers found human bones near the stone. An archaeological excavation of the site led by Paul Garwood took place in 2008–09; it found that the megalith was placed in its present location only in the 15th or 16th centuries. The archaeologists found no evidence of a chambered long barrow at the location, and suggested that the Coffin Stone might once have stood upright in the vicinity. Location The Coffin Stone is in Great Tottington Farm, which is now used as a vineyard. As of 2005, the site was not signposted, but could be reached via a stile along the Pilgrims' Way. The Coffin Stone is situated about north-west of Little Kit's Coty House. It is also a short distance north of the Tottington springhead. Context The Early Neolithic was a revolutionary period of British history. Between 4500 and 3800 BCE, it saw a widespread change in lifestyle as the communities living in the British Isles adopted agriculture as their primary form of subsistence, abandoning the hunter-gatherer lifestyle
