The Cueva d'en Xoroi is a large complex of caves which has been converted to a discotheque, halfway down the cliffs in Cala'n Porter. Legend has it that the Cova d'en Xoroi cave was once home to a merman. The story goes that Xoroi appeared from the sea and took shelter in the cave. Soon after, local houses were robbed and a girl, soon to be married, disappeared. One year, the island became covered in snow and footprints appeared. On following the prints a search party found a man and a woman living in a cave with their three children. The man and his eldest son threw themselves into the sea and the women and her other two children lived the rest of their lives in the local village. visitors can visit the caves during the day and in the evening the cave is turned into a night club playing ambient music. The dance floor is built into the cave entrance, partly inside the cave and partly above the sea. For more information and opening times please visit the link above.
