It is located on the Váh river, in the Ilava Basin, between the White Carpathians and Strážovské vrchy mountains, at an altitude of 242 metres.

The town's cadastral area is composed of Dubnica and "city part" Prejta, annexed in 1973.

[citation needed] Sometime in the 15th century the village passed to the rule of the Trenčín Castle.

At its height, the camp housed more than 700 Roma prisoners, most of whom had been used as slave labor in the nearby factory and to build a dam on the River Vah.
