The Tower of Cerrano (Torre di Cerrano) is 2 kilometres from the town centre, at the town's southern border with Silvi Marina. It was built in the 16th century by the Holy Roman Emperor, Charles V as a watch tower to guard against attacks from the Turks and others based in what is now Croatia, 100 km (62 miles) across the Adriatic. Today, the tower houses a modern sea-biology laboratory.
