A quick park and grab at Altar wedge tomb on the way to Mizen head
Wedge tombs of this kind were built in Ireland in the late Neolithic and early Bronze age, c. 2500–2000 BC.
Cremated burials took place in 2000 BC and pit burials c. 1200 BC. Around AD 200 a pit was dug and filled in with fish, shellfish and cdetacean bones, presumably as a ritual practice.
Despite the name, there is no evidence that the "altar" was ever used for SacrificeIt was used as a Mass rock in the 18th century AD. A holy well stood across the road.
It was excavated in summer 1989 by Dr. William O'Brien and Madeline Duggan. Material found included cremated human adult bones, a tooth, worked flint, charcoal, periwinkles fish bones and limpets.
