Near the town of Gort in County Galway, St Colman founded the Kilmacduagh Monastery in the 7th century. The site boasts a fine collection of churches and a well preserved but leaning round tower that stands 30m high.

Nearby, visitors can explore St John’s Church and Glebe House, thought to have been the residence of the abbot. The settlement, which became the centre of the Diocese of Kilmacduagh, also features the ruins of a cathedral.
