Janowiec Castle - a Renaissance castle built in between 1508 and 1526, on a steep Vistulan hillside in Janowiec (14,5 km south of Puławy), Lublin Voivodeship, in Poland.

[1] The castle was most likely built by Mikołaj Firlej at the beginning of the sixteenth century and expanded by his son, Piotr, the Voivode of the Ruthenian Voivodeship.

The bastion, used as a residence, was destroyed by the Swedish army in 1655 during The Deluge.

In 1928, an archaeologist, Leon Kozłowski had taken over the castle, but his plans to reconstruct the castle were stopped by the Second World War.

In 1975, the castle was bought by the Nadwiślańskie Museum in Kazimierz Dolny in Poland.
