Bizarre But True! Off the coast of Cancún, 400 concrete people stand motionless on the seabed. They’re not drowning victims. They’re not ancient statues. They’re the world’s first underwater museum—and they’re alive with coral, fish, and crustaceans that treat the sculptures like luxury apartments…
The Museo Subacuático de Arte (MUSA) exists because Cancún’s natural reefs were dying under the weight of 850,000 tourists each year. That’s the same visitor load as Australia’s Great Barrier Reef, except concentrated on a fraction of the space.
The Concrete Solution Nobody Expected
British sculptor Jason deCaires Taylor built MUSA in 2009 with a simple plan: give tourists something else to look at. The sculptures sit on previously barren seabed, areas that held zero appeal to divers and supported virtually no marine life. Over 420 square metres of dead ocean floor was transformed into glorious artificial reef.
The construction numbers reveal the scale. 120 tonnes of concrete, sand, and gravel. 3,800 metres of fibreglass. 400 kilograms of silicone.
Taylor spent 18 months creating the Silent Evolution installation alone, 120 hours working underwater. Some sculptures even weighed so much they required a 40-tonne crane placed on a commercial ferry to lower them into position!
The Fisherman Who Became Famous Underwater
Over 90 fishermen and women from Puerto Morelos stood still whilst Taylor cast their bodies in concrete for the installation.
One fisherman – Carlos, nicknamed Charlie Brown, now lives in the village and charges tourists 20 pesos to photograph him standing next to his underwater twin! His concrete doppelgänger made him locally famous. The real Charlie Brown capitalised.
The sculptures themselves contain deliberate design features most visitors never notice. Each “Banker” figure has a cavity between its buttocks—engineered specifically for crustaceans and eels to inhabit. Marine life treats the anatomical detail as prime real estate.
What Happens When Concrete Meets Ocean
The transformation timeline follows a predictable pattern. Within days: Algae forms a thin film on the sculptures. Within weeks: Small invertebrates like tunicates and hydroids appear. After several months: Slow-growing corals begin attaching to the textured surfaces.
The Silent Evolution installation now hosts more than 2,000 juvenile corals. The man-made structures created a complex reef system that researchers monitor regularly. Biomass increased on a grand scale. At a similar installation on the Great Barrier Reef, fish surveys show a 400 per cent increase in diversity and a 500 per cent increase in abundance since 2019.
The sculptures work because they’re made from marine-grade cement with a neutral pH. The material encourages coral colonisation rather than poisoning it.
Two Galleries, Different Depths
MUSA splits across two main sites:
Salon Manchones sits deeper – accessible to both divers and snorkelers who can hold their breath long enough. It contains 477 sculptures.
Salon Nizuc stays shallower, ideal for snorkelling without scuba certification. It holds 23 structures.
The museum obtained permits to sink 1,412 artificial habitats across 10 different areas over 50 years. So far, only these two galleries exist. The rest remains unbuilt, a future expansion waiting for funding…
Ready to Dive Into Living Art Yourself?
You don’t need advanced scuba certification to see MUSA!
Several operators offer Discover Scuba Diving Experiences – designed for complete beginners who’ve never breathed underwater. You get basic training, equipment and a guided tour through the submerged galleries.
The experience combines art appreciation with marine biology and adventure. You’re not just looking at sculptures—you’re watching an ecosystem colonise human forms in real time.
Tours typically last 3-4 hours, including equipment setup and the underwater portion. Visibility reaches as far as 30 metres on good days. Water temperature hovers around 26-28°C year-round. Lovely!
