The cathedral's crypt is an independent structure built before the upper church, dating back to 1157.
The campanile stands detached from the main body of the church, a common feature of regional medieval Italian architecture.
Pope Gregory IX consecrated the cathedral in 1225.
The structure incorporates spolia, or reused architectural elements from Roman-era buildings in the Rieti valley.
Saint Barbara's relics were moved to the cathedral in the 17th century to provide divine protection against natural disasters.
The cathedral serves as the seat of the Bishop of Rieti and the center of the Diocese of Rieti.
The Cattedrale di Santa Maria Assunta in Rieti is a Romanesque-style cathedral originating in the 12th century, with significant modifications through the 17th century. It features a separate campanile built in 1252 and a raised portico designed by Lombard masters. The interior follows a basilica plan with three naves and houses a notable crypt containing remnants of the original structure. Its crypt is particularly distinguished by its complex vaulted ceiling and historical Romanesque frescoes. The building is constructed primarily of local limestone. The cathedral sits on a site that has served religious functions since the early medieval period. It holds the relics of Saint Barbara, the patron saint of the city. Architectural layers include Renaissance modifications and a Baroque-style ceiling added in the 17th century.
