Victorian Guns
Fort Ricasoli

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.

History & Background

  • 1870s
    Three Armstrong RML (Rifled Muzzle Loader) guns installed at Fort Ricasoli as part of Malta's Victorian coastal artillery network. The guns commanded the southern approach to Grand Harbour.
  • Early 1900s
    As naval technology advanced, the heavy guns were decommissioned. Rather than salvage, the guns were pushed from the fort into the harbour approach during post-WWI clearance operations.
  • Today
    All three guns lie on sand at 2-12m, orientated roughly as they fell. The carriages have disintegrated but the gun barrels are intact. Dense marine growth covers the metal; schools of bream circle the barrels, and octopus are common in the breach mechanisms.

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.

Victorian Guns: what to look for

Victorian gun barrel No.1 at Fort Ricasoli, Malta
10m

Gun Barrel No.1

The largest of the three barrels, fully intact at 10m. Muzzle diameter approximately 200mm. Encrusted with calcareous algae and sponges; moray eel resident in the breach.

Victorian gun barrel No.2 partially buried in sediment
8m

Gun Barrel No.2

Partially buried in sediment but barrel clearly visible. The cast iron has developed a thick rust patina providing ideal substrate for invertebrates.

Victorian gun barrel No.3 at 12m depth
12m

Gun Barrel No.3

Deepest of the three, lying at an angle on the slope. The most isolated and the most densely colonised with sponges and fan worms.

Grand Harbour Approach

The broader reef area offers good macro photography, with nudibranchs, spider crabs, and cephalopods using the boulder field between the guns.
