HistoryThe 1873 tower is tapered in a style characteristic of Anglesey windmills. It is {{convert|33|ft}} high and {{convert|18|ft}} in diameter. It may have been constructed by an Anglesey stone mason, and it is possible that the tower itself was originally used as a windmill. The lantern and fittings cost £250 7s 6d, including the adaptation of an "earlier tower". The north-east door is flanked by small windows, and the two floors above also have small windows, but the top does not. The conical roof is slated and has a flagpole. The present lantern window is about {{convert|6|ft|6|in}} by {{convert|2|ft}}. The optic, silver-plated reflector and Fresnel lens are dated 1861 and were used into the 1970s. The lantern was originally lit by six Argand lamps with reflectors. A smaller, conical tower, with a domed top, can be found to the south-east, and may be an earlier structure. The walls are {{convert|6|ft|8|in}} in radius and {{convert|3|ft}} thick, with a door to the north-west, and show signs of cracking to the rubble-filled walls on the west. Neither tower is shown on the chart of Lewis Morris, dated 1800, but they both appear on the Ordnance Survey 1818-1823 2 inches/mile map. They both probably originated as unlit markers. The cottages nearby have been used as craft workshops, and the local community here once serviced pilot-boats and lifeboats. See also
