The castle is situated in the centre of the town and constructed in the style of a grand aristocratic palace-residence. It was last owned until 1944 by the Potocki family, and made infamous in late 16th century during the times of Stanisław Stadnicki, who was known as 'the Devil of Łańcut' "(Polish: diabeł łańcucki)" for his violent behaviour. After 1775 the palace was owned by Izabella Lubomirska, who extended it and had the interiors remodelled. The palace is currently a museum particularly well known for its large collection of historic carriages. Since 1961, a well-known classical music festival is held there annually.
