Globetrotting artist and photographer Jason deCaires Taylor (pictured) crafted 65 concrete-and-rebar figures—a combination of human forms and still lifes—anchored beneath Moliniere Bay. A snorkeling tour through the marine area allows travelers to get a fish’s-eye view of the works.

Taylor’s masterpieces also lie at the heart of an installation located between Cancún and Isla Mujeres in Mexico. In an effort to repair some of the region’s damaged coral reef, the artist partnered with the country’s Environment and Natural Resources Secretariat to open an artificial habitat where sea life could settle and thrive.

Nearly a dozen sunken ships spanning three centuries rest in the shallow waters of the Florida Keys National Marine Sanctuary. The underwater archaeological preserves give divers clues into maritime eras with submerged guides that encompass each vessel’s history, plus which aquatic inhabitants might be making their homes there today.

A city that once served as a trade port for the Roman Empire now lies 20 feet below sea level off the coast of Caesarea, Israel. Snorkelers and divers can examine such artifacts as marble columns, anchors, and shipwrecks from Phoenician and Byzantine eras as they make their way through 36 exhibits.
