Fatlips Castle is a 16th century stone rectangular tower house, of three storeys and a garret, founded by the Turnbulls of Barnhill. The entrance leads to a vaulted basement, with a spiral stair in one corner, which gives access to all the floors. At the garret, a round caphouse leads to an impressive corbelled parapet, which is rounded on the angles. In the 19th century, the tower was restored and renovated to be used as a shooting box and a private museum but sadly it is now once again ruinous. Nearby is Barnhills Tower and 4 miles east is Jedburgh Castle.
