Burt Castle

About

Burt Castle is a ruined castle located close to Newtowncunningham and Burt, two villages in the east of County Donegal in Ulster, Ireland. Historically it was sometimes spelt as Birt Castle. It is also known by the name O'Doherty's Castle, and should not be mistaken for O'Doherty's Keep near Buncrana.

The castle was constructed in the sixteenth century during the reign of Henry VIII. It was a traditional stronghold of the O'Doherty's, protecting the southern edge of their Inishowen Lordship. The design of the castle was strongly influenced by contemporary Z-Plan Scottish fortifications, and anticipated the style of buildings constructed during the Ulster Plantation of the following century.

During a disputed succession in 1600, the Crown's Governor of Derry, Sir Henry Docwra, backed the successful candidate, the fifteen-year-old Sir Cahir O'Doherty. O'Doherty wished to break free of the overlordship of Red Hugh O'Donnell and fought on the Crown's side during the Nine Years' War and was knighted for his bravery. Burt Castle was a vital post because it controlled a strategic area, allowing Docwra to bring in food supplies and to open up an offensive again O'Donnell.
