San Pietro cathedral, Minor basilica in Collesano, Italy.

San Pietro is a church in Collesano with a three-nave layout and a grand staircase leading to the entrance through an early 20th-century facade. The building displays a clear architectural structure with classical proportions that developed over several periods.

Construction began in 1543 and the building underwent several development phases over the following centuries. In 1983, Pope John Paul II granted it the status of minor basilica.

The church holds artworks from the 16th and 17th centuries, including frescoes by Gaspare Vazzano that depict scenes from the lives of Saints Peter and Paul. These works continue to shape the interior today and tell religious stories through their imagery.

The main entrance faces Piazza Duomo, with a secondary side door under a Gothic portal. The bell tower is the old defensive tower next to the church, used as such until 1912. The interior is entered from the top of the 17th-century staircase; services are held in the parish church, so time a visit outside Mass.

The central nave displays a crucifix from 1555 created by Vincenzo Pernaci, flanked by figures of the Virgin Mary and Saint John. This work showcases Renaissance artistic techniques and remains a focal point within the space.
