West Blockhouse Point Beacons, Pembrokeshire Coast National Park

The West Blockhouse Point Beacons are three leading light beacons, they perform the same function as a lighthouse and are situated on the promontory to the west side of the entrance to Milford Haven, and lie about a mile north-east of St. Ann's Head in Pembrokeshire, Wales. They consist of three octagonal reinforced-concrete towers of 30 feet, 37 feet and 46 feet in height, with sides 1.5 feet in width, surmounted by cantilevered octagonal concrete platforms on which stand sealed-beam lights. The lights are accessed by ladders which extend up the columns through an opening in the platform. Each column carries a steel daymark painted black and white. ()
