In 1734 the fortress was destroyed by Russian troops and replaced by Stanisław Potocki's palace in the Baroque style.
Until 1728 Tulchin was part of the estates of the Polish magnates of the Kalinowski family (other distinguished members of Tulchin family were Adam Kalinowski and Marcin Kalinowski), and then passed into the hands of Stanisław Potocki bypassing other Kalinowskis' branch, then in 1734 to Franciszek Salezy Potocki and his son Stanisław Szczęsny Potocki, who was the most memorable and infamous member of the Tulczyn branch of the Potocki family.
