The Norman castle of Doon appears to have been built on the site of the old Irish Dún Mughdhord,[2] The castle has almost disappeared.[2] in the townland of Dooncastle.[2] According to local accounts, the stones of the castle were used by Lord Sligo in the building of Westport House.[2]
The castle is on a hill 150 feet in height and gave excellent views to the northeast to Islandeady and Aille, where the other McPhilpin castles were.[2] The space on the hill is in the shape of an ellipse 40-60 yards x 20 yards.[2] The castle was rectangular and measured about 40 feet x 27 feet.[2] The space between the main castle and the outer fortifications was not great.[2]
