 After the Church Union of Brest was endorsed (in 1596) the Greek Catholic (the Uniate) Church was formed. Ukrainian people were divided into Orthodox and Uniates.
 Today 45 houses are located on the Market Square.
 Houses beyond Lviv’s walls, perhaps, were built already in the 16th c. and the end of the 18th c. built up.
