Madliena Tower
Malta
The 186th tallest tower in the world
Madliena Tower (Maltese: Torri tal-Madliena), originally known as Torre della Paulina, is a small watchtower in Madliena, limits of Pembroke, Malta. It was completed in 1658 as the fourth of the De Redin towers. The British built an artillery battery next to the tower in 1908–1909, and the tower and battery remained in use until World War II. Today, the battery no longer exists but the tower is in good condition.
