There are numerous Pictish houses in the parish, and a nunnery is said to have been located on the lands of Murkle, its site perhaps being marked by a small burn called Closters, a corruption of the word cloisters. At the top of the hill of Olrick are the remains of an ancient watchtower, and it is believed that a church called St. Coomb’s Kirk once stood near the eastern boundary of the parish. Its name is derived from its probable dedication to St. Columba. This church is supposed to have been the church of the united parishes of Olrig and Dunnet.
