Banj brdo: Banj brdo is a tourist resort in Banja Luka, from which you can see the entire city. This resort is rich in forests, walking paths and mountain biking, natural water sources for drinks as well as well-arranged recreation and leisure places. At the top of this hill (431 m above sea level) is the Monument to the Fallen Soliders Krajisnici, fighters against fascism. The monument is the work of Antun Augustinčić, one of the greatest Yugoslav sculptors. The hill top is about 5 kilometres from the city centre and offers a magnificent view of the whole city.

Fortress Kastel is located in Banja Luka and it is the oldest historical monument in this city. It was built on the left bank of Vrbas, between today's City Bridge and the crossing of the river Crkvena. In the past, Kastel was a strong military fortification and protected the Vrbas basin from enemy raids, primarily from the north. The fortress is surrounded by thick stone walls on all sides, where loopholes and observation posts are built. In the area of the fortress itself, a lot of archaeological traces have been found, from ancient times, through Slavic settlement to newer cultures. In Kastel, there is a Roman sarcophagus found in Šargovac, a Roman milestone from the former Salona-Servitium road. Today, at the site of the battle, many cultural events are held. There are numerous concerts and festivals held in the fortress, and some of them have become part of the manifestation tourism such as Demo fest and Fresh Wave.
