Next, Cooley graveyard overlooking Lough Foyle above Moville. This unusual high cross has a hole in it which has been suggested by some to be a hole for a sundial rod. Inside are the ruins of a church and a small stone roofed building known as the ‘skull house’. This is likely to be the grave of a founding saint as at Banagher and Bovevagh in County Derry. Archaeologists carried out investigations here in 2014 identifying circular boundaries of an early monastery around the graveyard. It is a very atmospheric place and well worth the visit.
