The Lismullin Iron Age enclosure: a place along the way

November 2011
Frank Prendergast, College of Engineering, DIT & School of Archaeology, UCD

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.
