The Kamianiec Tower is a 30-metre Gothic brick donjon built around 1271 — one of the oldest and best-preserved medieval defensive towers in Belarus and the entire former Grand Duchy of Lithuania. The tower stands on a slight rise above the Lesnaya River, its red brick walls still carrying arrow slits and battlements. A small museum inside, operated as a branch of the Brest Regional Museum, displays exhibits on the tower's history and the medieval Volhynian period.
Despite the nickname "White Tower" (a confusion, probably, with the white-walled fortifications of the Lithuanian Order), the tower has always been built of red brick. The interior is accessible via a wooden staircase and the battlements offer views over the surrounding Polesia countryside. Entry is cheap and crowds are minimal. The town of Kamianiec beyond the tower is quiet and workaday — this is a single-attraction stop, best combined with the Belavezhskaya Pushcha forest nearby.
