What Dubno Castle looked like in its prime.

Perched on a grassy promontory above the Ikva River, the castle presents a tall roughly coursed light-grey stone basal scarp supporting a higher red-brick curtain wall; a cylindrical brick corner tower rises above the wall, set off by a carved pale stone frieze band and capped with a dark domed roof and slender spire. At its prime the ensemble included continuous curtain walls with artillery bastions, a two-story palace and a church within the inner ward, all intact and serviceable.

Its story

The story of Dubno Castle.

Dubno Castle was founded in 1492 by Prince Konstantin Ostrogski on a promontory above the Ikva River, near the ancient Ruthenian fort of Dubno in Volhynia. Rebuilt in stone in the early 16th century under the Grand Duchy of Lithuania, it held a church, a two-storey palace and an array of 73 cannons, and the fabulous Ostrogski family treasury, which drew Crimean Tatar raids on at least two occasions in 1577 alone.

Prince Janusz Ostrogski, last of his line, rebuilt the castle in the early 17th century in the trace italienne, making Dubno the most advanced fort in the region; his palace still stands. During the Khmelnytsky Uprising the surrounding country saw heavy fighting between Poles and Cossacks, scenes Nikolai Gogol drew on in Taras Bulba, and the castle, passed to Prince Władysław Dominik Zasławski with the Ostroh inheritance, survived a Russian siege in 1660.

Dubno lost much of its military relevance in the 18th century. Prince Stanisław Lubomirski commissioned a plain two-storey palace in the 1780s from the architects Henryk Ittar and Domenico Merlini, though its interiors did not survive the First World War. The Lubomirskis sold the residence to Princess Boryatinsky in 1871, and in the 1920s the old barbican was turned into a prison, where about 550 political prisoners were executed by the NKVD in 1941.
