Chiesa di San Giovanni Battista dei Celestini (Church of St. John the Baptist), Bologna

Established by Pietro da Morrone, later known as Pope Celestine V, the Celestine monks arrived in Bologna in 1368 at the invitation of Antonio Galluzzi, who generously provided them with a monastery and a church dedicated to Saint John the Baptist. Over time, the complex underwent significant expansions and renovations, particularly during the 16th century, with its form largely preserved through an 18th-century reconstruction. Although the Celestines were disbanded in 1797, the church remained in use for religious services.

Originally intended to house the meeting hall of the Council of Thirty, plans for adapting the convent included demolishing certain buildings owned by Pompeo Fontana to create additional space; however, these plans were never realized. Instead, in September 1798, the convent was repurposed to oversee the administration of the lottery. Subsequently, it served various functions such as hosting the Registry office, conscripts' bureau, and archives of suppressed religious entities. In the mid-19th century, it underwent renovations to accommodate the School of Engineering Application and presently serves as the home of the State Archives.

Although the exterior may not be particularly striking or remarkable, the intricate and somewhat dramatic frescoes on the walls and ceilings certainly make the visit worthwhile. The artworks found on the main altar and in the side chapels are also worth admiring.
