Underground Bologna: a journey into the four Crypts


Bologna is a mysterious city full of hidden treasures. Under the surface, there are extraordinary places: come and discover the four crypts of Bologna!

The crypt of San Zama

Under the Abbey of SS. Naborre and Felice, there is the crypt of Saint Zama. Dedicated to the first bishop of Bologna, this crypt is a fundamental place for the first Christian community of Bologna. It is said that, in 270 AC, Zama himself wanted the renovation of a previous church, in order to dedicate it to St. Peter. Currently, the Cathedral dedicated to St. Peter is located in Indipendenza street: discover it in our article The Metropolitan Cathedral of San Pietro in Bologna: What’s to know?.

The church then took its current name with Zama’s successor, Bishop Faustiniano, who increased the fame of the current basilica.

Initially, people believed that the church was the first cathedral of Bologna, since the first Bolognese bishops were buried there. In fact, it is possible that the building stood above one of the first Christian cemeteries, where the bodies were interred as a cause of the ban on burial within the city walls.

The crypt of Saint Zama as we know it dates back to the 11th century, when it was configured as a place of prayer for the Benedictine monks. The crypt is made up of three apses, three naves and three rows of Corinthian-style columns, probably the result of the reuse of other buildings.

An interesting curiosity concerns the presence of windows. In fact, it is strange to find them in an underground crypt: this peculiarity is probably due to the fact that originally it was not located underground. Later,the Poor Clare nuns occupied the place and built a church above it, transforming the previous structure into a real crypt.

In addition, the Abbey of SS. Naborre e Felice was also the seat of the Military Hospital of Bologna.

The crypt of Saints Vitale and Agricola

The crypt of SS. Vitale and Agricola is located under the homonymous church, in St. San Vitale 50. Read also A Trip to the Ancient Jewish Ghetto of Bologna: the church is just a few minutes of walk away from the Jewish Ghetto and the Two Towers!

According to the tradition, the current church would rise on the remains of the ancient arena of the Roman Bononia, where gladiator shows and executions took place. In fact, the church takes its name from the two Saints Vitale and Agricola, Christian martyrs under the empire of Diocletian.

The crypt was built in the 11th century AC, right on the remains of a previous ancient Roman basilica. Centuries later, during the Napoleonic era, the building was destroyed. Later, the church of SS. Vitale and Agricola was bought by the Countess Cornelia Rossi Martinetti, who transformed it into a literary circle. In the so-called Orto delle Esperidi very famous international artists and writers met, including Foscolo, Monti, Canova, Leopardi and many others. In a short time, this club became one of the most important cultural salons in Europe.

The parish was then rebuilt in 1824 and, six years later, the crypt was rediscovered that we can still admire today.
