Since traditional popular architecture is increasingly disappearing from the area, an authentic ethno-household,  built in Knežica in 2012., constitutes a rare reminder of not-so-long-passed times, constructed with the aim to preserve the rich history, culture and tradition of local peasentry. The household, designed as a museum exhibition, is located half-way between Kozarska Dubica and Prijedor, and it occupies cca 2000 sq. m. There is also an amphitheater where many cultural events take place during summer.
