Description

The Lighthouse on Admiralty Pier is a Grade II listed structure, approximately 14.6 meters high. It is a three-storey tower made of tapering ashlar masonry, with the windows covered at the time of inspection. The lantern is notable as the second oldest in Wales, following the Point of Ayr lighthouse, featuring three tiers of square panes and a copper roof topped with a finial. The gallery has bellied iron railings and is supported by a moulded cornice of the tower.
