Ruins of the Sanguszko Palace, Iziaslav
Ruins of the Baroque residence of the Sanguszko princes, built in 1754–1770 to a design by Paolo Fontana on the headland between the Ponora and the Horyn, on the base of the Novyi Zaslav castle.
On the headland where the Ponora flows into the Horyn, in Iziaslav's New Town, stand the ruins of the residence of the Sanguszko princes. Here stood the castle of the Zaslavsky princes: according to turist.km.ua, in 1637 it consisted of a masonry gate and a palace with bastioned earthen fortifications. In the early 18th century the castle was rebuilt by Paweł Karol Sanguszko, and in 1754–1770 his widow Barbara Sanguszko built a new Baroque palace on this base to a design by the Sanguszkos' court architect Paolo Antonio Fontana (travel.24tv.ua, ye.ua). The palace, with numerous halls, picture galleries and a theatre, is said to have received King Stanisław August Poniatowski (travel.24tv.ua). In the 1870s the family sold the residence to the russian authorities: according to ye.ua, to bring the title-stripped prince Roman Sanguszko back from Siberian exile; according to turist.km.ua, the seller was Roman Damian Sanguszko. Until the 1990s there were barracks, officers' quarters and warehouses here, and everything of value was taken away (ye.ua). In November 2018 part of the walls collapsed, and in June 2020 another roughly 50 sq m fell (turist.km.ua). The shell of the palace, a covered courtyard with arcades and the palace bridge survive (travels.in.ua). A few years ago the monument of national significance was taken into ownership by the Iziaslav hromada; a project for emergency stabilisation works costing about 2 million UAH was to be presented at the end of February 2022, but the full-scale invasion got in the way (ye.ua, 30.04.2026).
Address: Iziaslav, Tarasa Shevchenka St, right bank of the Horyn, New Town (travels.in.ua, 13.03.2025). The grounds are neither private nor locked: access is free (travels.in.ua, 13.03.2025), round the clock (discover.ua), but the structure is unsafe — the floors between storeys have not survived, and at the end of 2024 signs reading “Danger! No entry” were put up on the arch (ye.ua, 30.04.2026); visitors report a recent collapse of a load-bearing wall and broken glass inside (discover.ua). View from outside only, do not go in, keep children away from the walls. Beneath the palace are unexplored underground passages; about half the walls have collapsed in the last 50 years (turist.km.ua, 28.08.2022).
