Three Victorian-era Rifled Muzzle Loader cannons rest on the sandy seabed at the entrance to Grand Harbour, dropped during harbour clearance operations in the early 20th century. At 2-12m they are accessible to Open Water divers, yet the setting is extraordinary: Valletta's fortifications rise above the surface, and the guns themselves are genuine 19th-century naval ordnance still intact on the sand.

The Victorian Guns are one of Malta's most accessible dives and one of its most historically unusual. Three 10-tonne cast-iron barrels on sand at a maximum of 12m, within a UNESCO World Heritage harbour setting. The site connects directly with the Grand Harbour dive cluster: a natural pairing with the HMS Maori or Fort St Elmo Reef for a full day of Valletta diving.
