Sopu Tower
Malta
The 186th tallest tower in the world
Sopu Tower (Maltese: Torri ta' Sopu), also known as Isopu Tower, San Blas Tower or Torre Nuova, is a small watchtower situated on the cliff between San Blas and Daħlet Qorrot in Nadur, Gozo, Malta. Isopu Tower was the last watchtower to be built in Malta, apart from the tour-reduits of the 18th century. It is one of four surviving towers on Gozo, with the others being Xlendi Tower, Dwejra Tower and Mġarr ix-Xini Tower. The earlier Garzes and Marsalforn towers were destroyed in the 18th and 19th centuries.
