From this 16th-century defence tower at Ibiza's southernmost tip, you can glimpse the islands that speckle the Es Freus strait separating Ibiza and Formentera. Among them are Illa des Penjats (Hangman's Island), where captured pirates were once sent to the gallows, and Illa des Porcs (Pig Island), where plump pigs smuggled over from Formentera were once kept.
