A municipality in the province of Pesaro-Urbino, located about twenty kilometers from the sea, whose territories also include the tiny district village of Cerbara, is crossed by the River Metauro. It is a center rich in history with the presence of several testimonies of the past, such as the ancient walls built in the XV century. The center is devoted to agriculture and significant is the local production of olive oil and DOC wines such as Sangiovese, but also features the presence of small industries for the manufacture of textiles, glass and iron.
Where today stands Cerbara, probably was the site of a more ancient village built in the V century and destroyed by the Goths. The survivors of the massacre founded a better located and more easily defensible new settlement on a hillside nearby. Until 1100, Piagge was part of the territories of the Abbey of San Paterniano in Fano, while in the XII century it became part of the Vicariate of Mondavio. Over the centuries the domain of the town was ceded in fief to several noble families, such as: the Ubaldini, the Malatesta, the Della Rovere, the De 'Medici. In subsequent years, it was acquired by the Papal States, and shared the same historical events of the entire region, until it was finally incorporated into the Italian State.
