Burt Castle

History of Burt Castle

Burt Castle, with its commanding view of Lough Swilly, was built during the mid-1500s as a stronghold to protect the southern portion of Ó Dochartaigh land. It was inhabited alternatively by the Ó Dochartaighs and by the English when the Ó Dochartaigh were allied to them. The holes in the castle are from practice shots fired by a British warship during World War I.

Visit Burt Castle!

  • The castle sits in the middle of a busy farm, privately owned by some friendly folk, so it's easy to miss visiting while taking a trip around the Irish countryside, unless you purpose to go there.



The O'Doherty Heritage website is designed to be your place for all things Ó Dochartaigh. Whether your name or ancestry is from a Doherty, Dougherty, Daugherty, Docherty, Dogherty, if your family used another spelling of our name, or if you're from one of our related Donegal families, such as the McDevitt/McDaid, McBride, McConlogue, or others–we welcome you to the O'Doherty Heritage website!

The vision of the O'Doherty Heritage is "Telling our story, uniting us together." This was the same vision of our ancestors, the Ó Dochartaigh patriarchs, when they established our Clan motto, Ár nDúthchas–which means 'Our Heritage'. Below are the goals of O'Doherty Heritage:


  • Share our heritage with our entire Clan

  • Research, document, & bring our history to life

  • Curate a digital Clan genealogy research library


  • Encourage quality genealogical research

  • Promote clan identity and pride in our heritage

  • Facilitate communication amongst our clanfolk
