Porto Venere is a town located on the Ligurian coast of Italy in the province of La Spezia. It comprises the three villages of Fezzano, Le Grazie and Porto Venere, and the three islands of Palmaria, Tino and Tinetto. In 1997 Porto Venere and the villages of Cinque Terre were designated by UNESCO World Heritage Site.
The ancient Portus Veneris is believed to date back to at least the middle of the 1st century BC. It has been said that the name refers to a temple to the goddess Venus which was sited on the promontory where the church of Peter the Apostle now stands. In Roman times the city was essentially a fishing community. After the fall of the Western Roman Empire, Porto Venere became the base of the Byzantine fleet in the northern Tyrrhenian Sea, but was destroyed by the Lombards in 643 AD. Later, it was a frequent target of Saracen raids. First indications of the existence of a castle date from 1113, and in 1161 the walls were erected.
