[1] In the 16th century, Borky Castle had high rough walls made of oak logs that surrounded and locked inside residential and outbuildings and four bastions that were placed on the cardinal points, with rows of loopholes at the corners.
A few kilometers from this place, on the ground that constituted a distinct barrier, deep trenches were dug, reinforced by a raft of thick logs, from which the modern name of the tract comes – Za Shantsiamy.
[4] When laying the foundations of residential buildings on Haharina Street (adjacent to the former castle) in 1970–1980, developers came across traces of fires, fragments of cold steel, arrowheads, Cossack clay pipes, and other artifacts, but they were lost because no archaeological excavations were carried out there.
[5] In the summer of 1649, during the Zbarazh siege and as a result of the articles of the Treaty of Zboriv, it, along with the town of Borek, which belonged to the great crown hetman Mikołaj Potocki, was destroyed to the ground.
After the first partition of Poland, Galicia became part of the Habsburg monarchy, and the kingdom with its starosta was abolished, so in 1784 Wiktoryn Zaleski was forced to buy the castle with the town of Borky from the Galician governorate and take it into his ownership.
[9] The map of the Austrian military cartographer Friedrich von Mieg Koenigsreiches Galizien und Lodomerien 1779–1782[10] clearly shows the outlines of Borky Castle with four bastions connected by a solid wall.
In the last quarter of the nineteenth century, Austrian military topographic maps of the territory of Velyki Birky still showed the conventional designation Schl from the German Schloss, which means a castle, palace, or estate without defensive fortifications.
In 1896, the priest Petro Bilynskyi [uk] noted: "There is no trace of the castle anymore, only very long beer pits dug in hard clay that are still in quite good condition.
