The Jewish synagogue in Łańcut, located right by the palace fence, stands on the site of a previous sacred building. The brick-built, simple-shaped synagogue was created in the 18th century at the initiative of Stanisław Lubomirski, who, having control over the construction process, fitted it into the landscape of the surroundings, not allowing it to overshadow the town hall or churches. Renovation in the 19th century added a characteristic staircase to the women's gallery. Damages caused during the German occupation and extermination of the Jewish population turned it into a warehouse, which deteriorated, and only survived thanks to the efforts of Dr. Władysław Balicki. The interiors have been gradually renovated since the 1960s. Currently, it is a historical building forming part of the Łańcut Castle Museum.
