St. John's Archcathedral
In 1944, German forces drove a tank packed with explosives into the nave. What you walk into today was rebuilt from rubble.

Poland's only archcathedral, this 14th-century Brick Gothic church on Świętojańska Street is a national pantheon where Dukes of Masovia were crowned and buried, and where King Stanisław August Poniatowski swore the oath of the 1791 Constitution. After the Warsaw Uprising, a German Vernichtungskommando blew up what the tank left standing. The reconstruction earned UNESCO World Heritage status alongside the Old Town.
What to look for
- The current Brick Gothic exterior replaced the English Gothic Revival building that stood here until 1944 and was obliterated during the Uprising — by WWII the 19th-century rebuilding had erased the original medieval form
- Ducal tombs inside: the church served as coronation and burial site for the Dukes of Masovia from the 1300s onward
- The Armenian Catholic chapel, founded in the 18th century after Armenians fleeing the Polish-Ottoman War settled in Warsaw
Enter from Świętojańska Street in the Old Town; the Jesuit Church stands immediately beside it, and the Royal Castle is a short walk away.
