Based on the world record nomination from America Records Institute (AMRI) and Decision No.WK/USA.INDIA/930/2022/No.386, World Records Union (WorldKings) officially declared Neptune Memorial Reef as the “The world's first artificial reef cum underwater columbarium” on November 24, 2022.
Neptune Memorial Reef lies 12 meters below the surface of the water, with complete with stone roads, soaring gates, and crumbling ruins. Originally named Atlantis Memorial Reef, he undersea cemetery was designed by Florida artist Kim Brandell and opened in 2007.
Covering nearly 65,000 square feet of the ocean floor, Neptune Reef is also an underwater columbarium, sponsored by the Neptune Society, a cremation company. Cremated remains are cast into concrete memorials and placed within the sunken necropolis, where divers can explore or visit with loved ones. This is also where Bert Kilbride, once recognized as the "World's Oldest Diver", is interred here in a place of honor at the top of one of the entry columns at the Reef gate.
Now Neptune Memorial Reef is also attracting recreational scuba divers, marine biologists, students, researchers, and ecologists from all over the world.
