Sigismund's Chapel is a royal chapel of the Wawel Cathedral in Kraków, Poland. Built as a funerary chapel for the last members of the Jagiellonian Dynasty, it has been hailed by many art historians as "the most beautiful example of the Tuscan Renaissance north of the Alps". Financed by King Sigismund I the Old, it was built in 1519–33 by Italian architect Bartolomeo Berrecci.
