At the northeastern end of town, a block back from the Platja Es Port, this stone-and-glass swirl of a building is part aquarium, part interpretation centre for the offshore marine environs of the Parc Nacional Marítim-Terrestre de l'Arxipèlag de Cabrera. The visit ends with a climb up a spiral ramp that wraps around an extraordinary mural by Miguel Mansanet, based on 16th-century Mallorcan maps of the Mediterranean.
