The castle is located on the top of the mountain and can be seen in many places in the city. It can be reached on foot or by cable car. Tickets have several different specifications and are selected according to your needs. The interior of the castle is dangerous, the road is very steep, and it is not easy to climb up and down. There is a Chinese voice guide. The first room has a model of fortress in various periods, explaining in detail the construction process of the fortress and the role of the archbishops. Next, follow the voice and visit the cells, stairs, "bulls", etc. The most important thing is to climb to the top and overlook the entire city.
