It is located on a hill in the village of Rudare, which is 11 km away from Kursumlija, on the Nis-Pristina road. A wall about 100 m long and about 10 m high can be seen on the site. It is composed of huge horizontal basalt pillars of pentagonal cross-section, properly arranged on top of each other. It is a geological phenomenon, whose age is estimated at several tens of millions of years. It is believed that the wall was formed as a result of the eruption of a mega volcano that was located in the Radan area.
It is a unique geological phenomenon in Serbia. The phenomenon is rare in the world, it is registered in the Czech Republic and Iceland. With this in mind, the wall on Branko’s tower can become a special and unique tourist attraction of the Kursumlija municipality.
Archaeological excavations at this place have confirmed the existence of the fortification. According to folklore, the seat of Branko Mladenović, the father of Vuk Branković, was located on this site, after which the site was named.
