The palace in Kozłówka was built in the 18th century for Michał Bieliński, but it experienced its greatest splendor at the turn of the 19th and 20th centuries, when the Zamość Estate was established in these areas. In the times of Konstanty Zamoyski, the palace in Kozłówka was one of the most beautiful aristocratic residences in old Poland. Its beauty continues to delight today. The Zamoyski family owned the property in Kozłówka until 1944. Since then, the property has been in the hands of the Polish state.
