The Cooley Cross is located just outside the perimeter walls of an ancient graveyard near Moville. This is an early example of a High Cross and dates to the 8th century AD. The cross stands 10 feet high, is plain, and has an odd-looking hole on its top. This hole is thought to have contained a peg serving as a ‘gnomon’ for a rudimentary sundial and so the vertical shadow indicated the hour of noon. There is a cross with a similar hole on the greater Aran Island where the vertical shadow line is marked. At the base is a large flat stone containing a crude representation of a human foot, traditionally ascribed to St. Patrick himself. These types of hole-stones date back to pagan times and are thought to be used during marriages when couples joined hands when making vows.
