The Cancún Underwater Museum is a series of pH-neutral marine concrete sculptures by Jason deCaires Taylor placed underwater off the coast of Isla de Mujeres and Cancún. The figures are based on members of the local community.The project began in November, 2009, with placement of a hundred statues in shallow waters of the Cancún National Marine Park, which had been damaged by storms. The artist planned the sculptures as artificial reefs with fire coral planted in the sculptures. (via Imgur and Wiki)
