Niedzica [ɲeˈd͡ʑit͡sa], (Slovak: Nedeca, German: Netzdorf, Hungarian: Nedec) is a resort town in Nowy Targ County of Lesser Poland province, Poland, located on the banks of Lake Czorsztyn. It is famous for Niedzica Castle, also known as Dunajec Castle, an important centre of Polish-Hungarian relations built between the years 1320 and 1326 on foundations of a prehistoric roost. Originally, the village almost exclusively inhabited by the Slovak ethnic group (part of Hungary, between 1939 and 1945 belonged to Slovakia) was in 1920 and again in 1945 affiliated to Poland. The town lies approximately 6 kilometres (4 mi) north-east of Łapsze Niżne, 21 km (13 mi) east of Nowy Targ, and 75 km (47 mi) south of the regional capital Kraków.Niedzica developed into a popular tourist destination as a result of the construction of the dam on Dunajec river between 1975 and 1997. Facilities close to the town centre include: the border crossing with Slovakia (2 km distance), the Pieniny hotel, the tourist apartment complex "Pod Taborem", Exhibition Hall, and the boat station for the raft ride down Dunajec River Gorge to Szczawnica resort town.
