Gravensteen Castle
The Gravensteen (Dutch; literally 'Castle of the Counts') is a medieval castle at Ghent, East Flanders in Belgium. The current castle dates to 1180 and was the residence of the Counts of Flanders until 1353. It was subsequently re-purposed as a court, prison, mint, and even as a cotton factory. It was restored over 1893 - 1903 and is now a museum and a major landmark in the city. Built by Count Philip of Alsace, count of Flanders, soon after he returned from the Crusades with images of similar crusader castles in the Holy Land. If its walls (2m thick), battlements, and turrets failed to intimidate attackers, the count could always turn to a well-equipped torture chamber inside. You can view relics of the chamber in a small museum in the castle. Climb up to the ramparts of the high central building, the donjon, which has great views of Ghent's rooftops and towers.
