Caldey Island Trig pillar and lighthouse (also rusty tank)

A named place photographed at this map point in Pembrokeshire.

Caldey Island, located off the coast of Pembrokeshire, has a long history of monastic settlement, including a 13th-century Cistercian monastery and a later Carmelite priory. The island's trig pillar and lighthouse are notable for their roles in navigation and surveying, while the presence of a rusty tank suggests 20th-century military activity in the area.
