Caldey Island

Caldey Island Lighthouse is located at the southern end of a small island about two and a half miles offshore from Tenby.

The Lighthouse tower is built of limestone and is brick lined. It stands 56ft tall with the light standing 210 ft above high-water mark.

The light was first exhibited on 26th January 1829 showing a fixed white light, produced by 20 Argand oil lamps mounted in polished reflectors.

In 1885 a clockwork mechanism was installed, and the light was subsequently converted to an occulting character.

With improvements to gas technology in the 1920s some Trinity House lights were converted to automatic operation and Caldey Island was installed with Acetylene, using a Dalen sun valve. At this stage, the keepers and families left the island, and an islander was employed as an Attendant.
