This slab was found in 1925 at Ballalough (IOMHER 0933.00). It bears a simple pecked and gouged cross on one face. The associated keeill site, Cronk Keeillane, stood on a natural mound about 270 yards west-northwest of Poortown (Peel Road) railway station, south of the highroad to Peel, in the Quarterland of Ballakilworrey; the old highroad cuts through the keeill's burial ground, and lintel graves have been exposed on both sides of the road as well as in a field further to the west-southwest.
