The Boim Chapel is a monument of Lviv architecture. It was built as a crypt in 1609-1617 (according to other sources between 1609 and 1615) for the Boim merchant family. At first, this territory belonged to the city cemetery. The construction was started by George Boim, a Lviv merchant and usurer of Hungarian origin, and completed by his son Pavel-George. The wall facing the Latin Cathedral is covered with intricate carvings, the interior is also decorated with alabaster carvings. Portraits of Georg Boim and his wife Jadwiga have been preserved on the eastern façade. The wall of the western facade is completely covered with stone carvings. The sculptural group "Pieta" by J. Pfister is of high artistic value - an outstanding work of Lviv art of the 17th century. The chapel bears a resemblance to the Sigismund Chapel near the Wawel Cathedral in Krakow.
