Underwater museums are unique attractions that combine art and marine conservation. These museums feature sculptures and installations submerged in oceans or lakes, creating artificial reefs that promote marine life. Visitors can explore these sites through snorkeling or diving, experiencing art in a new environment. The purpose of underwater museums is to raise awareness about environmental issues, such as coral reef degradation and ocean pollution. Notable examples include the Museo Subacuático de Arte in Cancún, Mexico and the Underwater Sculpture Park in Grenada. These sites not only provide artistic experiences but also contribute to marine ecosystem restoration.
