The Chapel of the Boim family at the Cathedral Square is a late Renaissance monument; it has no analogues, neither in Ukraine nor in the rest of Europe.

Built between 1609 and 1615, founded by mighty merchants, Jerzy Boim of Hungarian origin and his wife Jadwiga Ni¿niowska, the Boim chapel was finished by their son, Pawe³ Jerzy Boim.

The façade of the chapel is entirely covered with stone carvings featuring the Passion and the figures of Saints Peter and Paul.
