The best view on Portofino you will catch from the square in front of the church of San Giorgio on the lighthouse promontory: from this position you have a splendid overview of the port and the row of coloured houses with their typical decorations. Portofino lies in a bay whose natural shelter is provided both by its shape and by Monte Portofino itself, which looks over the sea from a height of 600 metres and forms a three-kilometre ridge ending to the east at Punta del Capo. The church of the fortem of San Giorgio itself dates back to the 12th century but rebuilt after the damages of the last war, according to the eighteenth-century shape. A tombstone reminds that St. George's relics, here preserved, were brought by the Crusaders in the eleventh century. The fortress of San Giorgio lies almost in the centre of the promontory; it was built on the Genoese people's will and it was finished in 1557 The building was modified in the following centuries and restored by Alfredo D'Andrade at the end of the 19th-century.

In Portofino there is the church of San Martino, much remanaged in the last century; it keeps works by the Ligurian School. Noteworthy is also the medieval oratory of Santa Maria Assunta, built in the fourteenth century.
