Sri Lanka's coastline is famous for its golden beaches and vibrant marine life, but beneath the waves lies a new attraction that is capturing the attention of divers and conservationists worldwide. The Sri Lanka Navy has established three unique, eco-friendly underwater museums. These sites serve a dual purpose: they are spectacular new diving attractions and vital artificial reefs that promote coral regeneration and marine life conservation.
Trincomalee Underwater Museum (Sandy Bay)
Located off Sandy Bay beach and established on July 10, 2020, the Trincomalee Underwater Museum is Sri Lanka's second artificial reef project. Sunk at a depth of about 60 feet, the main attractions here are two decommissioned Navy gunboats: the Ex-SLNS Jagatha and Ex-SLNS Weeraya.
In addition to these imposing vessels, the site features replicas of ancient cannons and eco-friendly sculptures. Spanning a large area, these submerged features act as excellent substrates for coral colonization and provide a rich habitat for fish, making it a must-visit for certified divers. Key features include: two decommissioned Navy gunboats, eco-friendly sculptures, cannon replicas, and rich marine habitats.
Galle Underwater Museum
The Galle Underwater Museum was the first site created by the Navy, opened on June 17, 2020. Located near the Galle Harbour at a depth of 50 feet, it features an underwater sculpture park of artifacts and plaques made from eco-friendly concrete.
These installations encourage coral growth and act as breeding grounds for local fish species. The accessible depth of 50 feet makes this site perfect for both intermediate divers and snorkelers looking to explore a unique art exhibition underwater.
Nilwella Underwater Gallery
Established on April 10, 2022, the Nilwella Underwater Gallery is the shallowest of the three sites, resting at 10 to 30 feet. This makes it incredibly beginner-friendly and ideal for snorkeling.
Arranged to resemble a sunken town, the gallery contains numerous human-made sculptures, cultural figures, discarded vehicles, and aircraft parts. Over time, these eco-friendly concrete structures act as substrates for coral growth and create a thriving fish breeding habitat in the Southern waters near Nilwella.
