Niesytno Castle was a castle in the south-west of Poland, near the village of Płonina, situated west of Bolków. After the castle turned into ruins, Płonina Palace was built at the same site, though the place is still often referred to as Niesytno Castle. It has decayed over the years, and only its ruins have remained. It is in private hands and closed to the public, but is along the tourist Piastowskich Castle Route.
