Perched atop Guasco Hill, the San Ciriaco Cathedral stands majestically as the primary spiritual symbol of the city of Ancona. This outstanding monument of medieval architecture is one of the most fascinating examples of Romanesque style in Italy, harmoniously blending austere Western forms with elegant Byzantine and Gothic elements.

The cathedral building, constructed from light-colored Conero stone, features a Greek-cross plan, which is rare for this region. Its facade is adorned with a magnificent Gothic portal, while one of the oldest ogival domes in Europe soars over the central section. Thanks to its location, the cathedral serves as a natural lighthouse: its silhouette is the first to greet ships entering the port of Ancona.
The interior of the church is striking for its noble materials and mystical atmosphere. Red columns of Verona marble support high vaults, while soft light pours through the windows of the dodecagonal drum, illuminating ancient mosaics and frescoes. The cathedral is not just an open-air museum, but a living testament to the rich history of the Adriatic.
