St Tudwal's Lighthouse

St Tudwal's Lighthouse is a free-standing tower built in the 19th century, positioned on the central axis of the former keepers' accommodation, which is located in front of it. The tower stands 10.7 meters high and features a circular, tapering form with a lined-out render over stone. A heavy moulded cornice projects boldly to support the gallery of the lantern. The lantern itself has a ribbed cast-iron base, lattice glazing, and a domed roof topped with a ball-finial vent and weather vane. The gallery railings are made of cast iron and include fluted finials.

The entrance is located on the west side, facing the blocked rear entrance of the keepers' accommodation, and is accessed through a square projecting porch with an unmoulded cornice and blocking course. There are single windows on either side of the tower, each featuring projecting sills and lintels, while the transomed windows have raked back upper lights. The Trinity House arms are displayed in relief above the north-facing window.

Inside, there is a service room on the ground floor, with a steep cast-iron ladder staircase leading to the lantern floor. This floor is of standard type, supported by radial cast-iron beams and features an outer gridded walkway. At the top of the staircase, there is a cast-iron lotus railing. The optic, dated 1876, is marked with a maker's plate from Chance Brothers & Co Lighthouse Engineers and Constructors near Birmingham. The cast-iron support for the optic has moulded open panels at the base and an open-work frieze above a moulded cornice, and it carries a beehive optic.
