Cadw's description

Located on a rocky promontory within the grounds of Trearddur House, set back from the W side of Lon St. Ffraid.

Second World War pillbox fortification; part of the defences of the town of Trearddur Bay.

Circular plan. Built of local rubble, with rubble plinth on concrete foundations; head of wall has rubble set on end to give effect of folly or garden architecture, concealing concrete roof. Square-headed doorway and openings around circumference; doorway protected by curving screen wall.

Included as unusual example of this fortification type, to a design believed to have been used only on Anglesey.
