Casquets lighthouses, Lighthouse complex on Les Casquets rocks, Alderney, Channel Islands.
Three stone towers stand on the rocky Les Casquets, with the north-west tower remaining the primary navigation light source for ships in the English Channel.
Trinity House granted Thomas Le Cocq a lease in 1723 to construct three lighthouses, which started operating with coal fires on October 30, 1724.
The three towers, named St Peter's, St Thomas, and Dungeon, guided ships through dangerous waters where numerous vessels met their fate, including SS Stella in 1899.
The lighthouse functions with solar panels, wind turbines, and LED technology, maintaining an operational range of 18 nautical miles across the Channel waters.
The original design featured three separate towers in a triangular formation to differentiate it from French lighthouses on the adjacent shores.
