Kastel Fortress

The Kastel Fortress in Banja Luka is medieval but is situated on the site of previous fortifications going all the way back to Roman and even pre-Roman times. The fortress is relatively well-preserved, and is one of Banja Luka's main attractions, situated on the left bank of the Vrbas river in the very center of town. 

The site has been fortified since Roman times, but the current walls and architecture were made mainly in 1490s by Ottoman reign.
