Łańcut Castle rises amidst the ancient trees of an old landscape garden, beyond the town's eastern limits. Once upon a time the castle was fortified. A ring of bastions cornered with towers which defended the entry can still be seen, though they have been significantly changed in numerous reconstructions. A small library pavilion built in the late 18th century adjoins the castle from the north and to the south there is an early 19th-century conservatory.
