Chapel of the Assumption of the Virgin Mary at Clementinum

The Chapel of the Assumption of the Virgin Mary, better known as the Italian Chapel (Vlašská kaple), is a small oval church tucked between St. Clement's Cathedral and St. Salvator Church inside the Klementinum complex in Prague's Old Town. Unlike its two much larger Jesuit neighbours, this chapel was built for an entirely different community — and it shows in both its size and its purpose.

Who was this chapel actually built for?

The clue is in its nickname. The Italian Chapel served Prague's resident Italian community — merchants, craftsmen and artisans who had settled in the city in growing numbers by the second half of the 16th century. The Jesuits, who moved into the former Dominican monastery attached to St. Clement's in 1556, had already been preaching to this community in Italian since 1569, using an older, makeshift chapel and oratory at their college. As the community grew, it warranted a proper, permanent building of its own.

When was it built, and by whom?

Construction began in 1590 to a design by the architect Ottorino Mascarino, carried out by Domenico Bossi. The main structure was finished by 1597, and the chapel itself was consecrated in 1600 — going up almost in step with the neighbouring St. Salvator Church, though on a far smaller and plainer scale. It's a Mannerist building on an oval floor plan, topped with a dome and lantern that today is largely hidden behind the surrounding Klementinum buildings. The chapel shares an entrance portico with St. Clement's Cathedral and stands directly behind St. Salvator's sanctuary, which is exactly why it's so easy to mistake for one of its neighbours.

What does the interior hold?

The original Mannerist decoration from the turn of the 17th century gradually gave way to Baroque redecoration. Wall frescoes depicting the Seven Mysteries of the Virgin Mary survive from 1607, painted while the chapel's original Mannerist scheme was still in place. The dome, on the other hand, carries a fresco of the Assumption of the Virgin Mary from the 1770s, sometimes attributed to Giovanni Pietro Scotti, though the attribution isn't firmly settled. Illusionistic painting covers the interior pillars, visually stretching out the chapel's compact oval space. The building is listed as a Czech cultural monument and has undergone conservation work on its facade and stucco decoration in recent years.

Is it worth seeking out on its own?

The chapel has no separate visitor route — it's structurally fused into the rest of the Klementinum and has no independent entrance for outside visitors. Its interest lies less in scale than in what it says about old Prague: a city where, alongside its Czech and German populations, a distinct and organised Italian colony was large and prosperous enough to warrant its own dedicated place of worship inside the Jesuits' own Klementinum complex.

Frequently asked questions

How is this chapel different from St. Clement's Cathedral and St. Salvator Church? These are three separate buildings within one complex. St. Clement's Cathedral and St. Salvator Church are large, freestanding Jesuit churches, each with its own facade and entrance. The Chapel of the Assumption is much smaller, built on an oval plan, and was raised specifically for Prague's Italian community rather than the general congregation.

Where does the name "Italian Chapel" come from? From the community it served — Italian merchants, craftsmen and clergy living in Prague, for whom the Jesuits had already been holding services in Italian before the building itself even existed.

Who designed the chapel? The design is attributed to architect Ottorino Mascarino, with construction carried out by Domenico Bossi between 1590 and 1597.

What frescoes are inside? The walls carry frescoes of the Seven Mysteries of the Virgin Mary from 1607, while the dome holds a fresco of the Assumption of the Virgin Mary from the 1770s.

Can you visit the chapel separately, without a Klementinum ticket? No. It has no dedicated visitor entrance and isn't set up as a standalone stop on any tour route — it's fully integrated into the surrounding Klementinum buildings.
