SS Peter and Paul Church is one of the oldest stone buildings in Minsk, constructed on a narrow street Rakauskaja and remained up till now as a monument of architecture of the 17th century. The building was started in 1611 and was finished after two years. During wars and religious conflicts the church served as a fortress. It explains the thickness of its walls, a high arrangement of windows above the ground and presence of loopholes. In 1795 in the church there was Minsk Cathedral named after Russian empress Ekaterina, who gave money for reorganization. In the middle of the 19th century during the restoration the temple got some features of pseudo-Russian style. From 1991 services in church are renewed. The church is a monument of an early Baroque with elements of the Renaissance style.
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.
