The Virgin Mary's Assumption Church was blessed in 1631 with a participation of Kyiv metropolitan Petro Mohyla. Next to the church, which is the pearl of Ukrainian sacral architecture of the Renaissance, there is Kornyakt's tower. In old times it was the highest building in Lviv. In the XVII-XVIII centuries the Virgin Mary's Dormitior church was a distinguished center of the Christian culture of Ukraine, a sacral place of the Lviv Orthodox Brotherhood.
