Ta' Kenuna Tower
Malta
The 186th tallest tower in the world
Ta' Kenuna Tower (Maltese: Torri ta' Kenuna) is a semaphore tower on the cliffs near Nadur on the island of Gozo, Malta. It was built by the British in 1848, as one of three semaphore towers in Malta. The tower was restored in 2005, and now houses a beacon to warn ships of their proximity to land, as well as a number of communication antennas.
