From the outside of the city wall, there is a passage at about the height of the university church behind, which leads down a staircase to the inside of the city wall. One looks from here to the back of the so-called professors' houses in the cloister yard. Also at the height of today's university church, which was formerly the church of the monastery of the Holy Cross, located in the upper part of the ramparts is a beautifully planted area with garden flowers and shrubs. The upper path along the city wall is lined with tall trees and, depending on the season, flowering shrubs that grow on the city wall. To the lower area lead paths and stairs. The moat looks like a small, longish pond. Here, in the morning hours, there are only a few visitors. You can watch the relaxing activity of the ducks and listen to the song of the birds. Halfway up and down there is also a playground.
