Jason de Caires Taylor is the founder and creator of several underwater museums. Motivated by concern over the health of the ocean and redressing climate change, his idea was to draw divers away from the most fragile and delicate parts of coral reefs.
His five tonne concrete sculptures, which he sinks to the sea floor, encourage coral and algae growth over time. The first museum, created in 2006, was off the west coast of Grenada in the West Indies is listed as one of the top 25 wonders of the world by National Geographic.
Since then 500 of his sculptural works have been submerged off the coast of Cancun, Mexico and other submarine sculpture parks completed in the Bahamas and Canary Islands. One of his most recent works is on the foreshore of the river Thames in London. The sculpture is of four horseback riders and they can only be seen at low tide.
