Co-cathedral

The Cathedral of Santa Maria Assunta features a three-nave layout with an elevated transept and a tower rising above the structure. A connected chapel beneath the main level preserves early Christian elements from centuries past.

Early Christians established a subterranean chapel in the 6th century, using spaces in the existing structure. Medieval builders later constructed the upper church on top, adding the distinctive three-nave layout and elevated transept.

The interior holds religious artworks spanning several centuries, drawing visitors to observe their craftsmanship and detail. These pieces shape how people move through and experience the sacred space.

The church is generally accessible during daytime hours, with both the main interior and the subterranean chapel open to visitors. A connected museum space displays additional religious objects and works from the surrounding area.

The structure sits upon the foundations of an ancient Roman temple once dedicated to Castor and Pollux. This link between pagan and Christian periods remains visible in the base layers of the building.
