Area Marina Protetta Regno di Nettuno

Palazzo dell'Orologio (Clock Tower) is also worth a visit. It is an 18th-century building, located in the main street of Ischia Ponte, and inside it houses the Museo del Mare, with nautical charts, navigation and fishing instruments, artefacts and objects that trace the history of the island and of the "Village of Celsa" (the current Village of Ischia Ponte).
