Ownership of the estate passed from Stanisław Koniecpolski to two generations of the Lubomirski family, who neglected it as their interests lay elsewhere, and after the death of Teodor Lubomirski in 1745, sold it on.[2] In 1747, Stanisław Poniatowski converted the lower castle into a horseshoe shaped classical palace. After the Poniatowski family relinquished their ownership, at the end of the 18th century, it came into the possession of the Błażowski family.[2] In 1863 Krzysztof Błażowski donated the crumbling palace and gardens to the Sisters of the Immaculate Conception order, for the establishment of a girls catholic secondary boarding school, Jazłowiec College, which continued, with interruptions for wars, until the Invasion of Poland in September 1939.[2] From November 1918 the estate was briefly under the administration of the Ukrainian People's Republic until the summer of 1919 when it came under the aegis of newly independent Poland. The Sisters hung on in the property during World War II, despite two of them becoming the victims of murder by Ukrainian nationalists. In 1945 the entire estate came under the Soviet Union and the order of nuns was finally expelled from the region in 1946.
After the war, the classical palace was variously a prison, a garrison and a sanatorium. In the 1990s the Immaculate Conception Sisters were allowed to return to one wing of their former property, to run a retreat centre and a sanctuary for their foundress, Blessed Marcelina Darowska, who is buried in the palace. Currently, the castle is managed by the Castles of Ternopil Oblast National Reserve.[3]
