Comino Island – this 3.5 sq. kilometer island is located between the islands of Malta and Gozo. Those interested in Maltese history would be immediately drawn to St. Mary’s Tower – the most visible structure on the island (dating back to 1618, when the Knights of Malta built it as part of Comino’s defense). It also served as a prison for spies during Napoleon’s occupation, and was also put to use during World Wars I & II. With this building now being the property of the Armed Forces of Malta, it has become a tourist destination. The other notable structures on this small island are a Roman Catholic chapel that was also built in 1618, and St. Mary’s battery (built as part of a network of batteries built along the coastline of the other Maltese islands).
Nowadays, there’s some tourism here, since it attracts snorkelers, divers, and swimmers (the island’s Blue Lagoon area being a huge draw for such visitors). Hollywood movies such as “Troy”, “The Count of Monte Cristo” and “Swept Away” were filmed here (with St. Mary’s Tower doubling as the Chateau d’If in the “Monte Cristo” film)
