Barnhills Tower is a 16th century stone rectangular tower house, founded by the Turnbulls. The tower is ruinous and now only stands to the height of the first floor, the vaulted basement is pierced by gunloops and there are traces of a spiral stair in one corner. Built against the north bank of a small burn and over looked by Fatlips Castle, its dense cover of trees, makes it best viewed in winter. 8 miles south-west is Hawick Castle and 10 miles north is the Commendator's House.
