Constructed in the early 17th century on the grounds of what was a city cemetery; this quaint structure was originally intended for use as a crypt by the Boim family. George Boim, a Lviv merchant and moneylender of Hungarian origin, started the project and his son, Paul-George, put the finishing touches on what would become a permanent feature in Lviv’s stunning centre. The side of the chapel is decorated with fretwork that gives the impression that the entire structure has been turned inside-out. Fresco portraits of George Boim and his wife Jadwiga can be viewed from Halyts’ka vul. The site has been protected by UNESCO since the 1970s.
