Saint's Peter and Paul Church

The church is located at ulica Grodzka 52a, Kraków, right in the historic Old Town. It was founded by King Sigismund III Vasa and built under the supervision of Jesuit architects. The layout is a Latin‑cross plan, with a single nave, side chapels, and a dome over the crossing. Its interior features a late‑Baroque main altar from 1735, elegant stuccoes, and a baptismal font that dates back to 1528. In the crypt, there is a pantheon-like mausoleum that now serves as a resting place for eminent Polish cultural figures, scientists, and artists making the church not only a place of worship but also a national monument of memory.

Entrance to the church is free for visitors (donations are welcome), but because it remains an active parish, access may be restricted during services. Dress modestly cover shoulders and knees and keep volume low out of respect. On Thursdays, there is a special attraction: the church hosts a demonstration of a Foucault pendulum, the longest in Poland, which elegantly illustrates Earth’s rotation. Investment in modest footwear is wise, as you may explore the crypt and walk across the nave. Photography is generally allowed, though flashing lights might be discouraged because of delicate interiors.

Saints Peter and Paul Church sits in Kraków’s Old Town and is easily reachable on foot if you stay nearby. From the Main Market Square (Rynek Główny), it's a pleasant 5‑10 minute walk along historic Grodzka Street. For those farther away, several tram and bus lines stop nearby, followed by a brief walk. If you use a taxi or ride-share, the drivers often know the church well just ask for “Kościół Piotra i Pawła, Grodzka.” Given its central location, walking is often the simplest and fastest option.
