San Costanzo stands in a panoramic position among the rolling hills of the Marche region, with views stretching across the Adriatic Sea, the Metauro Valley and as far as Fano. It is a village that still preserves the intimate atmosphere of a medieval hill town, surrounded by a landscape where nature, history and local traditions exist in perfect harmony.

The area was already inhabited in the 8th century BC, while the origins of the present-day village were recorded in the 15th century as an important castle under the jurisdiction of Fano. Today, the historic centre still retains the charm of its ancient fortifications, enclosed by Malatesta walls built between the 14th and 15th centuries. Parts of the old castle survive in the form of several towers, which during the Christmas season host the distinctive Esoteric Nativity Scene, one of the area’s most unusual and fascinating traditions.

At the heart of the village stands Palazzo Cassi, an elegant late 18th-century noble residence that now serves as the town hall. Inside, visitors can explore the Civic Art Gallery and the Archaeological Hall dedicated to the ancient protohistoric settlement and Picene necropolis, offering important insights into the long history of the area. The palace also houses the permanent exhibition of the “Maschere del Castello”, refined artistic masks created by Anna Lorenzetti and featured in renowned carnival parades throughout Italy.

Other noteworthy landmarks include the Teatro della Concordia, the historic town theatre that still hosts a programme of performances and plays, as well as the Collegiate Church and the Church of Sant’Agostino.

San Costanzo is also deeply connected to its traditional celebrations. Every year, on the first Sunday of Lent, the village hosts the historic Sagra Polentara, considered the oldest festival of its kind in the Marche region and now well beyond its two-hundredth edition, attracting visitors from across the surrounding area.
