Brough Castle (Caithness)

It is believed to date from the 12th to 14th centuries.

The foundations of the castle are on the landward end of a long rocky promontory about 1⁄4 mile (400 m) north of the east end of the hamlet of Brough.

A trench some 40 feet (12 m) wide and 10 to 12 feet (3 to 4 m) deep has been dug across the neck and on either side of the rock; in rear of it has been a range of buildings separated by a narrow courtyard or passage.

The promontory tails away seawards to a shelf of rock.
