The Bulwarks, Porthkerry, Iron Age promontory fort in Porthkerry, Wales.
The Bulwarks covers 4.1 hectares with three defensive banks and ditches forming a trapezoidal structure overlooking the Bristol Channel from steep cliffs.
Archaeological excavations in 1968 revealed three rectangular buildings from the late third century CE, along with twelfth-century pottery in the surrounding soil.
The fortification demonstrates the military engineering capabilities of Iron Age communities, with evidence of continuous occupation from 200 BC through the Roman period.
Visitors can reach the monument through Porthkerry Caravan Park or by taking a steep path from the beach through forested areas.
The cliff edges surrounding the fort erode at 24.2 centimeters annually, gradually altering the shape and size of this ancient defensive structure.
