The Church and Celestine Monastery were built in the 1300s, in the hamlet once called Plorzano and now Santa Caterina.
The simple architectural lines and structure reflect the canons of the Benedictine Order, far from the glitz; over the centuries, however, the church was enlarged and in the 1600s made more “Baroque,” with a grand staircase and the addition of frescoes, stucco and carvings to its interior.
You can also visit the adjoining small medieval cloister, with a square plan, the portico, and the Great Cloister, with four corner stone pillars and 14th-century capitals.
The Monastery was closed in the late 1800s, while the Church, after a period of deconsecration, was restored and returned to the city and worship in 1939.
