The national monument at Lismullin was discovered by archaeologists in 2007 during topsoil stripping for a section of the M3 motorway. The most significant finding was a series of buried sockets that indicated the former presence of a large c. 80 m diameter multi-ring structure with a formal entrance avenue and other pit and post features.
This is now described as a rare example of a timber post-built ceremonial enclosure. It is securely dated to the Iron Age in c. 600 BC, and to have had a probable ritual and ceremonial purpose rather than a burial or habitation function. This lecture examined the role of astronomy in prehistory and then focus on how geo-spatial analysis of the excavation data was used to unlock the construction method and the likely use and role of the monument at Lismullin in the Iron Age.
In its Heritage Lectures the Lismullin Institute seeks to explore various aspects of our local heritage so that visitors to the Lismullin Conference Centre and our neighbours will have a greater knowledge and appreciation of the history and attractions of their surroundings. The Lismullin Institute is pleased to invite you to some or all of these public, stand-alone lectures in Lismullin Conference Centre. The Lectures will begin at 8pm and light refreshments will be served afterwards.
