Kraków’s Dominican Monastery is one of just remaining three in the world which has been running continually since its foundation. It was set up in 1222 by St Jacek Odrowąż, giving rise to the Polish Dominican Province. To mark the 800th anniversary, the monastery is opening a museum showcasing interiors previously unavailable to the public (including Romanesque cellars) and cultural treasures collected by the brothers over the centuries. The most precious item is Poland’s oldest quartet of stained-glass windows, dating back to the turn of the 14th century, previously deposited at the National Museum in Krakow. Also notable is the collection of 13th-century objects, dating back to the monastery’s early days, discovered during an architectural dig.

Entry is free, but you need to book a pass for a specific time and date, either using the Online Booking System or in person at the shop at the Dominican Liturgical Centre.
