and the small exhibition "Panorama through the centuries", so the administration expected no more than 10,000 visitors. Almost one third, 20,000, were foreign tourists. Two piers, one larger and other smaller, are placed in the Danube, but the touristic boats were not allowed to dock until the fortress was officially declared a port area in April 2018, when the international cruise ships began to dock. Also, there are plans for bringing the model cannons into the cannon tower. In April 2018, four towers were planned to be open for public, 6, 7, 8 and 10, or the cannon tower, but the deadline was extended to the end of the year. The tower 8 will host a three-floor exhibition dedicated to the knights, with a section devoted to the Polish knight Zawisza Czarny. Plans include the joining of the attractions in the vicinity, like Đerdap national park and prehistoric site Lepenski Vir, in one tourist arrangement. As number of visitors grew significantly since the full re-opening of the fortress, various works are planned in the surrounding area to the west, in the direction of the modern town of Golubac. They include new restaurants, pension-type facilities, new roads, bicycle and pedestrian paths and arrangement of the touristic settlement Dedinski Raj ("Golubac's Dedinje"), between the town and the fortress. Also, the beach will be adapted along the Danube's bank. Based on the accessibility and difficulty, the complex is divided in four zones: green (the lowest section; open for all visitors), blue (only for adults; towers 3 and 4), red (only for adults with assigned special escort), and black (only for adults with assigned special escort, and applying specific safety procedures - physical fitness, special attire and footwear, absence of acrophobia and ophidiophobia, allowed access for only two visitors at the time; Hat Tower).
