St. Mary's Tower
St. Mary's Tower was founded in 1601-1622 on the southern shore of the island of Comino. It provided control and protection for communications between the islands of Gozo and Malta. The two-storey building erected on a square plan has a total height of 20 m, of which 8 m falls on a massive, steeply falling foundation (base). The building has 6-m thick walls, which effectively protected it even from artillery fire.
A stone staircase leads to the main entrance of the tower - between their gable and the gate a 3-meter space was left, which could only be overcome by a wooden bridge. In an emergency, the bridge could easily be lifted or burned. Originally, the tower was surrounded by a ditch and a defensive slope, the remains of which have survived to this day.
From 1829, the tower was abandoned. Occasionally it was used as an observation point and a place for the stationing of small troops fighting against smuggling and illegal fishing. It had a restaurant in the early 21st century and has been open to visitors since 2004.
