Why visit Navy Underwater Dive Museum

• Navy-Built Artificial Reef and Museum: It is a unique concept wholly constructed by the Sri Lanka Navy. It serves a dual purpose as an artificial dive site for tourism and a marine life regeneration project to promote the growth of corals and fish breeding.
• Exhibits Include Naval Wrecks and Sculptures: The museum features historical maritime exhibits, including two sunken Navy gun boats (Jagatha and Veera), military equipment, and large sculptures (like ancient cannons and architectural columns) handcrafted by naval personnel using eco-friendly materials.
• "Atlantis-Like" Underwater City Experience: Divers describe the experience as being in an "underwater city" or "Atlantis," due to the arrangement of the columns and artifacts on the sandy bottom, creating an eerie and fascinating environment.
• Fast Marine Life Integration: Since being opened in 202 , the site has shown a rapid growth of marine life, with the sunken gun boats already serving as excellent habitats for fish species like groupers and batfish.
• Located Off Trincomalee's Sandy Bay: The museum is located off the popular Sandy Bay Beach in Trincomalee, a region on the East Coast famous for its clear waters, making it an ideal destination for certified divers (PADI Open Water required) during the diving season.
