The Janowiec Castle is among the most magnificent and most beautifully located buildings of this type in Poland. It is over 500 years old and for centuries it served as the residence of significant noble families of Firlejs, Tarłowos and Lubomirskis. The castle throbbed with life from the early 16^th century until the end of the 18^th century; however, in the 19^th century the owners rotated more and more often, and eventually, the castle was abandoned and fell into ruin. Its last owner (and at the same time, the last private owner of any castle in Poland) was Leon Kozłowski, who managed the castle in the years 1931–75. The former bastion castle was taken over by the Nadwiślańskie Museum in 1975, and preserved as a permanent ruin. It is currently the main tourist attraction in the region. Its majestic outline on the top of the hill accompanied by the small town located below composes one of the most picturesque views in Poland.
