The Cooley Cross is located on the outskirts of Moville in County Donegal. This was the location of a 6th-century monastery founded by St.Finian. The cross dates to the 8th or 9th centuries a.d and stands about 10 feet high. It is plain in appearance but 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. The base of Cooley cross is also peculiar as it is a large flat stone containing a crude representation of a human foot, traditionally ascribed to St. Patrick. There is also a perforation, about four inches in diameter, near one end and this may have also been used as a hole-stone which is now used to support the cross. Hole-stones date back to pagan times and are thought to be used when couples joined their hands through them when making vows. Very Romantic.
