Gjirokastër Castle dominates the town and overlooks the strategically important route along the river valley. It is open to visitors and contains a military museum featuring captured artillery and memorabilia of the Communist resistance against German occupation, as well as a captured United States Air Force plane to commemorate the Communist regime's struggle against the 'imperialist' western powers.
The citadel has existed in various forms since before the 12th century. The first of the defenses were put in place by the Despots of Epirus, an off-shoot of the Byzantine government, who established the basic towered structure of the castle. Extensive renovations and a westward addition was added by Ali Pasha of Tepelene after 1812. The government of King Zog expanded the castle prison in 1932.
Today it possesses five towers and houses, the new Gjirokastër Museum, a clock tower, a church, a cistern, the stage of the National Folk Festival, and many other points of interest.
The castle's prison was used extensively by Zog's government and housed political prisoners during the Communist regime.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
