Archikatedra św. Jana Chrzciciela i św. Jana Ewangelisty

The Cathedral of St. John the Baptist and St. John the Evangelist is one of the oldest Baroque buildings outside of Italy, modeled after Rome's Chiesa del Gesù.

The interior impresses with rich Rococo and Baroque-style decorations, including illusionist polychromes by Joseph Meyer.

An unusual attraction is the acoustic sacristy, where a whisper from one corner can be heard in the opposite corner. The treasury hides richly decorated costumes and church jewels, and the crypts are where deceased monks and important Lublin personalities rest.
