Gori Castle is a medieval citadel in Georgia, standing above the city of Gori on a rocky hill. The castle first appears in the 13th century records but archaeological evidence shows that the area had already been fortified in the last centuries BC. The fortress controlled major strategic and economic routes and accommodated a large garrison. In the 16th century the Ottomans captured it to overawe Tbilisi. In 1598 the Georgians besieged it to no avail; in 1599 they feigned a relaxation of the siege for Lent before launching a surprise attack at night to regain the citadel. The fortress continued to change hands between the Georgians and the Persians in the 17th century.
The citadel acquired the present-day form under the Georgian kings Rostom of Kartli in the 1630s and Erekle II in 1774. After the Russian annexation of Georgia in 1801, the fortress was garrisoned by a Russian grenadier battalion, but its importance gradually declined and the fortifications went defunct.
Gori Fortress was significantly damaged by the earthquake in 1920. The best preserved structure is Tskhra-kara ('the Nine-gated'), which looks to the west, and is adjoined by the supplementary walls on the south and east.
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.
