Tallest traditional lighthouse

The tallest lighthouse purpose-built exclusively for aiding navigation of ships at sea is the 82.5-m (270-ft 8-in) Île Vierge Lighthouse (48.6°N, -4.5°W) located 1.5 km (0.9 mi) off the coast of Finistère, Brittany, France. Made of stone (also making it the tallest masonry lighthouse), it was constructed between 1897 and 1902.

The Île Vierge Lighthouse is made from two types of local rock: kersanton and granite.

The tapered stone tower reaches 73.42 m (240 ft 11 in) and the remaining height of the structure is made up by the lantern housing the lenses. The maximum diameter is 15 m (49 ft 2.5 in) at the base and 6 m (19 ft 8 in) at the apparatus room beneath the lantern; the interior diameter throughout is 5 m (16 ft 5 in).

The world's tallest lighthouse overall, as listed by the National Geospatial Intelligence Agency’s “List of Lights”, is the 133-m-tall (436-ft) Jeddah Port Control Tower in Saudi Arabia. The concrete and steel tower was built in 1990 primarily as an observation tower to monitor and coordinate traffic in the port. Its light has a focal height of 137 m (450 ft).
