The town's name is most probably derived from the Slavic word knyaz ("prince, duke"), most likely after a local ruler that defended the population in the area during the Ottoman rule of Bulgaria. Knezha is the third-largest town in the province, after Pleven and Cherven Bryag, and is the administrative centre of a municipality. The town was located in Vratsa province until 2001, when a boundary change shifted the town into Pleven province.
A local landmark is the 17-metre (56 ft) steelChristian cross constructed on a hill overlooking the town. The cross' construction was financed entirely by donations. It has luminescent lighting bodies attached to it and is illuminated in blue at night.[1] The cross is similar to the larger Millennium Cross above Skopje. Knezha also has a historical museum and an amateur theatre performing in the local community centre (chitalishte). The Institute on Maize of the Agricultural Academy is based in Knezha; it was founded in 1924.
