The Tower of Cerrano ("Torre di Cerrano") is 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, across the Adriatic. Today, the tower houses a modern sea-biology laboratory. Future plans for this location by the Ministry of Environment, the Administration of the Province, the Administration of the City and the University of Teramo include a Sea Park.
