Doon Fort is an ancient ring fort hidden away on Doon Lough near the coastal village of Portnoo. It was built 1500 years ago and it?s walls stand 4.8m high and are 3.6m thick. The fort covers most of the island. As well as ?Doon Fort? it is sometimes called ?The Bawan? or ?The O?Boyle Fort? as it became their stronghold in the 16th century. It was also the scene of the murder of Conor O?Boyle in 1530 who was slain by a rival O?Boyle family member! The fort is now on land belonging to a friendly local farming family. During the holiday season they have small boats available for hire. The McGrath Clan Gathering 2020 will provide you with the opportunity to explore the historic and cultural richness of the North.
