The cathedral contains the remains of Saint Eusebius, the patron saint of the city and the diocese of Biella.
The floor plan features a single wide nave, a design characteristic of the late Gothic transition period in northern Italy.
The baptismal font dates back to the 15th century and is one of the few original interior elements that survived later renovations.
The Cathedral was officially elevated to its current status as the seat of a diocese in 1772 by Pope Clement XIV.
The central portal is decorated with terracotta reliefs, a material commonly used in regional construction during the late Middle Ages.
Biella Cathedral, formally known as the Cathedral of Saint Stephen (Cattedrale di Santo Stefano), serves as the primary seat of the Bishop of Biella. Construction on the current structure began in 1402 and was completed in 1502, replacing an earlier medieval church located on the same site. The architecture is primarily Gothic, though it underwent significant Neo-Gothic restorations during the late 19th century. Its most prominent exterior feature is the tall, slender bell tower. Inside, the cathedral houses numerous artistic works, including frescoes and altarpieces commissioned by local noble families. It stands as a significant example of religious architecture in the Piedmont region. The site remains an active place of worship and the ecclesiastical center of the local diocese.
