St. Rochus Cemetery (Rochusfriedhof) was created in late 1510s to bury the victims of the plague epidemic of 1517-18. To avoid spreading the disease, city authorities decided to build the cemetery at some distance from the city, so St. Rochus is located outside the old city wall. The cemetery was finally consecrated on 21 March 1519. St. Rochus Chapel was built in 1520–21. The architect was Hans Beheim the Elder, who also built a chapel for Johannisfriedhof, another old Nuremberg cemetery.
References:The Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
