The rains of Zhvanets fortress rise on a steep picturesque bank of the Dnister. In the place where Zhvanchyk River runs into the Dnister, the confluence of two rivers formed a steep cape with a steep slope, on which the remaining northern tower of the old fortress has been preserved.
Fortifications on the site of Zhvanets fortress first appeared in the ancient times, and in the 15lh «entury, the first stone castle was built here, to be repeatedly reconstructed during the 15th – 16th centuries. Such attention to the fortress is not surprising, as it had a strategically important location to protect the Polish-Lithuanian Commonwealth borders from Tatar and Turkish troops.
The fortress played a great historical role during the national liberation war of Ukrainian people. It was the place of a great battle between Cossack troops and the Polish army led by King Jan Kasimir. The Cossacks besieged the Polish fortress from September to December 1653. At a crucial moment, the Polish troops received support from Tatars under the Crimean Khan Islam Girey III, bribed by gold and the royal permission to plunder Ukrainian lands. Unable to resist both armies, Bohdan Khmelnytskiy retreated from Zhvanets fortress to Pereyaslav for negotiations with Russia that resulted into the Treaty of Pereyaslav. Once the fortress had lost its strategic importance in the 18th century, it declined gradually and only its ruins have survived up to nowadays.
