Basilica di San Paolo Maggiore

The church of St. Procolo dates back to the 11th century when it was rebuilt by the Benedictine monks of Cassino. The Gothic cross vaults were built later, between 1383 and 1407, by order of Abbot Giovanni di Michele. Between 1535 and 1557, the architect Antonio Morandi, known as Terribilia, built the fifth bay of the church, the choir and the bell tower. In 1744, the architect Carlo Francesco Dotti directed the internal transformation, which was redone after 1826, after the church had been closed to worship for almost thirty years due to Napoleonic suppressions.

The church of San Salvatore was built between 1606 and 1623 on an ancient medieval church, the seat of the Canons Regular of Santa Maria in Reno. The present building was built by Vincenzo Porta, according to the project of the Barnabite father Giovanni Ambrogio Mazenta and the architect Tommaso Martelli. The façade, with its simple lines, houses in four niches the terracotta statues representing the evangelists, made by Giovanni Tedeschi and originally painted in imitation bronze. Three other copper statues are placed at the top.

The Basilica of San Petronio is a major church in Bologna, one of the largest brick Gothic buildings in the world. Although construction began in the late 14th century, the building, which was to be larger than St. Peter's Basilica, is largely unfinished since the 17th century.
