The conjectured site of an Early Medieval keeill or chapel and burial ground, thought to date to the period AD500-1000.  No trace of the keeill has ever been found, but about 1907, during ploughing, lintel-graves were exposed at the site.  One grave, 100 metres southeast of Ballalergy was recognised by a stone slab, measuring 2 metres by 0.6 metres (noted on field copy of the 6 inch Ordnance Survey map by P.M.C. Kermode in the Manx Museum). The site was visited by J.R. Bruce in 1963 who stated that no foundations or burial-ground banks were evident in the even surface of the pasture field.
