Tallest lighthouse

The 133-m-tall (436-ft) Jeddah Port Control Tower in Saudi Arabia, although not primarily built to aid navigation, is listed by The National Geospatial Intelligence Agency’s “List of Lights” and surpasses in structural height any other traditional and non-traditional lighthouses in active use. The concrete and steel tower was built in 1990 and has a focal height of 137 m (450 ft); it produces three white flashes every 20 seconds.

The tallest traditional lighthouse (purpose-built exclusively to aid navigation of ships at sea), meanwhile, is the 82.5-m (270-ft 8-in) Île Vierge Lighthouse, on an islet off Finistère, Brittany, France, which was built between 1897 and 1902.
