Caldey Lighthouse, Navigational lighthouse on Caldey Island, Pembrokeshire, Wales.
The circular limestone structure reaches 17 meters in height with walls measuring nearly one meter thick at the foundation level.
Trinity House commissioned Joseph Nelson to construct this maritime beacon in 1829 for £4,460 to guide vessels in Carmarthen Bay.
The lighthouse stands near a Cistercian monastery, where monks have maintained religious activities on the island since the early 1920s.
The lighthouse beam extends 13 nautical miles across the water, producing three flashes every twenty seconds to guide maritime traffic.
This facility remained the final Trinity House lighthouse operating on acetylene gas until its conversion to electrical power in 1997.
