St. Simeon’s and St. Anna’s Orthodox Cathedral was designed by architect N. Chagin and built during 1890-1892, with the financial support of Russian Czar Alexander III. The altar and foundation remained from the previous church which was built in 1774 after the design of architect F.B. Rastrelli. It was devastated in WWII and renovated between 1993 and 2003.
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.
