Ruins of Zviahel Fortress, Zviahel
The remains of the castle of Prince Kostiantyn Ostrozky above the Sluch, destroyed by the Cossacks in 1648.
The fortress stands on the high bank of the Sluch in the centre of Zviahel, on Lesi Ukrainky Square. Prince Kostiantyn Ostrozky received the lands of Zviahel in 1502 and built a castle here in 1507. In 1648 the stronghold was captured and destroyed by Cossack detachments, and the castle was never rebuilt. Fragments of foundations and walls remain of the structure; in the 1980s part of the fortress wall and one of the towers were restored. In 2020, on the basis of archival descriptions and archaeological surveys, a 3D model of the castle as of 1620 was created. Entry to the grounds is free, and the town tourist centre runs tours here with VR goggles and theatrical performances.
