Wedge Tomb

ryaner Jul 15, 2026

This is the updated note from the SMR at archaeology.ie. It was updated because the monument is now destroyed, obliterated by ignorance. Unbelievable!

There are 4 photos of the monument on the site here, taken in 2018, the year before its destruction, showing a fine wedge tomb with some of its roofstones in situ.

MA112-044---- : Megalithic tomb – wedge tomb : LISDUFF (Clanmorris By., Crossboyne Par.)
Description: In pasture, located at the break of slope on a N–facing slope, which falls to a flat expanse of lowlying wettish pasture. The views to SW, the direction in which the tomb faced, are not extensive, with ground rising to a low ridge in the middle distance. There is a rath (MA112-045----) 20m to SE in the same field, and cist (MA112-108----) is located 100m to SE. This wedge tomb, which is indicated on the 1929 OS 6-inch map as ‘Dolmen’, was destroyed in February 2019. There is now no visible trace at ground level. The tomb consisted of a gallery/burial chamber (L 9.5m; Wth 1.4m) defined by a double wall of upright slabs or orthostats, roofed by flat slabs. It was oriented NE–SW, with the entrance at SW, and was enclosed by remnants of a sod-covered cairn or mound (overall L c. 16m; Wth 7.5m at SW; c. 4.5m at NE) . The attached document includes a detailed description, plan and photograph of how the tomb looked when recorded by Ruaidhrí de Valera and Seán Ó Nualláin in Survey of the Megalithic Tombs of Ireland.
