MUSA Underwater Museum
Isla Mujeres · Mexico
MUSA — the Museo Subacuático de Arte — places over 500 life-sized concrete sculptures on a shallow sandy plateau between Isla Mujeres and Cancun, creating an eerie underwater gallery that doubles as an artificial reef. The sculptures are made from pH-neutral marine-grade concrete seeded with coral fragments, and after more than a decade underwater many are now substantially colonised by hard corals, sponges, and encrusting algae. Swimming through rows of human figures overgrown with coral is a genuinely uncanny experience that blurs the line between art installation and ecological restoration.
