Porto Venere is a town located on the Ligurian coast of Italy in the province of La Spezia. It is made up of three villages called Fezzano, Le Grazie and Porto Venere, and the three islands of Palmaria, Tino and Tinetto. This place is also a maritime gem and boasts pastel-coloured houses and a striking seafront. Its defining landmark, St Peter's Church, dramatically stands atop a rocky promontory, offering panoramic vistas of the Ligurian Sea. Don't miss stepping into Doria Castle, a medieval fortress, and the collapsed ruins of the Grotta dell'Arpaia from where the English poet Lord Byron started his swim across the Gulf of La Spezia to visit Mary Shelley in 1822.
