Brackenhill Tower is a peel tower, in the parish of Arthuret, in Cumbria, just north of the River Lyne. The site is about 2 miles (3.2 km) north of Kirklinton and 4 miles (6.4 km) east of Longtown, or 10 miles (16 km) north of Carlisle and 8 miles (13 km) east of Gretna Green, and is a good defensive position, with ravines to the north and south. Extensions were added in the 18th and 19th centuries, but the original tower has had little alteration. It is the only remaining example of a Scottish tower house south of the border with England, and became a grade II* listed building in 1957.
