Ta' Ġawhar Tower
Malta
The 186th tallest tower in the world
Ta' Ġawhar Tower is a round Punic-Roman tower in the village of Safi, Malta. The tower is the best preserved of the six Punic-Roman towers in Malta at approximately seven wall courses high. The tower was probably built at the time of the Punic Wars, although it continued in use during the Roman period before its destruction in the 3rd century AD.
