Saint Anthony's Lighthouse and Keepers Cottage

Saint Anthony's Lighthouse and Keepers Cottage is a lighthouse and keepers' cottage built between 1834 and 1835. The structure features painted granite ashlar walls and has paired chimneys on the landward northeast side.

The lighthouse is octagonal in shape and includes a covered passage leading to a two-room keepers' cottage at the rear. It stands four floors high, plus a lantern, and is constructed on bedrock. The base and flanking observation areas are finished with banded, rusticated ashlar, and it retains original bollards and iron rails. The lighthouse tower is slightly tapered and has windows on all four sides, featuring alternating 16-pane sashes and some blind windows. A moulded spray-deflecting cornice crowns the building, topped by a simple parapet balustrade and a 12-light lantern with a weather vane. The keepers' cottage is a single storey with a hipped slate roof and two sash windows.

The interior has not been inspected, but it is noted that the fog warning bell, which was the heaviest in Cornwall, was removed in 1854.
