Monellan Castle

Monellan Castle was a large castellated mansion, in Killygordon, County Donegal, Ireland. It was constructed in the 18th century for the De Lap (also spelt Delap) family, a British military family who acquired the estate in return for services rendered to the crown. The family also owned estates in Buckinghamshire, England.

During the 1930s, the castle and its estate was acquired by the Irish Land Commission which redistributed the land to local tenant farmers, as was the policy at the time. The castle was then, with support from the Irish Government, demolished.
