Ulysses was the first traveller to visit these islands according to the Odyssey and Homer was also one of the first visitors. Lipari is the largest and most populated, full of enchanting coves and beaches, the oldest part of the island, the castle, is a natural fortress built on a rock surrounded by sixteenth-century Spanish bastions. Here stood the primitive inhabited center, which dates back to ancient times, as evidenced by the Greek tower of the fourth century BC. The cathedral of Norman origins was rebuilt in the sixteenth century together with the castle dominates the town.
