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:Trenčín Castle is relatively large renovated castle, towering on a steep limestone cliff directly above the city of Trenčín. It is a dominant feature not only of Trenčín, but also of the entire Považie region. The castle is a national monument.
History of the castle cliff dates back to the Roman Empire, what is proved by the inscription on the castle cliff proclaiming the victory of Roman legion against Germans in the year 179.
Today’s castle was probably built on the hill-fort. The first proven building on the hill was the Great Moravian rotunda from the 9th century and later there was a stone residential tower, which served to protect the Kingdom of Hungary and the western border. In the late 13th century the castle became a property of Palatine Matúš Csák, who became Mr. of Váh and Tatras.
Matúš Csák of Trenčín built a tower, still known as Matthew’s, which is a dominant determinant of the whole building.
