Niedzica Castle also known as Dunajec Castle (Latin: Castrum de Dunajecz, Hungarian: Nedec Váralja / Nedec-Vár, German: Sub-Arx Unterschloss, Slovak: Nedecký hrad), is located in the southernmost part of Poland in Niedzica (Nowy Targ County in Lesser Poland). It was erected between the years 1320 and 1326 by Kokos of Brezovica on the site of an ancient stronghold surrounded by earthen walls in the Pieniny mountains. The Niedzica Castle stands at an altitude of 566 m, on a hill 300 m upstream from the Dunajec River mouth, measured from the center of the dam on Czorsztyn Lake. The outline of Niedzica Castle can best be viewed from the ruins of Czorsztyn Castle on the other side of the lake.
