In 2019, Australia lowered a 58-ton concrete greenhouse into the Great Barrier Reef; the 12-metre underwater structure became a living artwork and coral habitat

Nestled beneath the waves near John Brewer Reef in Australia lies an innovative Coral Greenhouse sculpture crafted from pH-neutral cement, designed to foster marine life. Observations reveal a remarkable increase in fish populations since its installation, highlighting its role in raising awareness and securing funding for essential reef conservation efforts. This project exemplifies proactive measures against pressing environmental challenges.
