Envision an underwater museum created by man. With no walls to hang paintings, how could this be done…and what’s the point? Developed for the Punta Nizuc National [marine] Park off the coast of Cancun and Isla Mujeres, Mexico, the Museo Subaquatico de Arte (MUSA), or Subaquatic Art Museum, is the answer to an important question: How do we preserve our deteriorating coral reefs? Not only is this museum a tourist attraction but it’s a nature preserve. Nearly open for exploration, the Cancun underwater museum will be the largest in the world when completed.
