Acicastello is another small sea village developed on the back of the Castle built in black lava stones. This Norman fortress is nestled atop a rocky spur on the sea. This place has been fortified since the Roman Age; destroyed on several occasions, it was rebuilt as a prison but now it is a Museum, collecting archaeological relics and mineral specimens. A splendid view over the faraglioni and the Lachea island can be enjoyed from its top.
