You may not have known the world needed one, but the very first underwater sculpture park was created by sculptor Jason deCaires Taylor in 2006. The British sculptor used casts of real people to create a cement world of people buried in the water off the coast of Grenada in the Caribbean. The most famous of the series features a collection of people holding hands in a circle. The strange sculpture park can be viewed by scuba divers or passengers on a glass-bottom boat tour.
