Perfectly nested in the natural paradise of the Monte Conero, this church overlooks the white limestone cliffs on which it is erected. In harmony with its surroundings, and partially concealed by the greenery, the church of Santa Maria di Portonovo is a true gem of Romanesque architecture, made of blocks of limestone from the Conero. The floorplan in the form of a Greek cross is divided up into a nave and four aisles, with a cupola split into two parts, square lantern and tambour, where the main source of light is represented by the characteristic mullioned double windows.
