Church of St. Bonaventure

The Church of St. Bonaventure is a Baroque sacred building standing in the northwestern part of the historic, once-walled town center of Mladá Boleslav in the Czech Republic. Attached to a former Minorite monastery and later home to a Piarist grammar school, the complex ranks among the town's most notable religious landmarks.

What is the history behind the church?

A Minorite monastery is believed to have existed on this site as early as 1293, though the friars' presence here was anything but peaceful — the monastery was plundered and burned during the Hussite Wars, forcing the monks to flee. The church visitors see today was not built until 1675–1711, most likely on the site of an earlier, now-vanished church dedicated to St. John the Baptist.

The building's ownership history mirrors the region's turbulent religious past. In 1496 the site passed into the hands of the Unitas Fratrum (Unity of the Brethren), who converted the church into an assembly hall for their congregation and turned the former monastery into a meeting house. It wasn't until 1784, under Emperor Joseph II's church reforms, that the monastery was handed over to the Piarists from nearby Kosmonosy, who relocated here together with their grammar school and gave the site a new, educational purpose for generations to come.

Since 1967 the church, together with the former Piarist monastery building, has been protected as a cultural monument. A major turning point in its modern story came in 2005, when the town of Mladá Boleslav became the owner of the church.

What can you see inside?

Today the interior serves as a ceremonial hall for Škoda Auto University. It hosts academic graduation ceremonies and matriculations, classical music concerts, exhibitions, weddings and other social events. It's a rare case of a secularized Baroque monastery church that avoided falling into disrepair, instead finding a lively second life as a venue for culture and higher education while retaining its historic architectural character.

How do you get there?

The church stands in the historic center of Mladá Boleslav, in the town's northwestern quarter, right next to the former monastery complex. The town lies roughly 50 km northeast of Prague and is well connected by train and long-distance bus, making it a convenient day-trip destination from the Czech capital. The old town where the church is located is compact and easy to explore on foot.

When is the best time to visit?

Because the building now belongs to Škoda Auto University and functions as its ceremonial hall, access to the interior depends on the university's event calendar — concerts, exhibitions and academic ceremonies. If seeing the inside matters to you rather than just the exterior, it's worth checking locally for scheduled events before planning your trip.
