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:
Considered to be one of the most imposing Roman ruins, Diocletian’s palace is certainly the main attraction of the city of Split. The ruins of palace, built between the late 3rd and the early 4th centuries A.D., can be found throughout the city. Today the remains of the palace are part of the historic core of Split, which in 1979 was listed by UNESCO as a World Heritage Site.
While it is referred to as a 'palace' because of its intended use as the retirement residence of Diocletian, the term can be misleading as the structure is massive and more resembles a large fortress: about half of it was for Diocletian's personal use, and the rest housed the military garrison.
The palace has a form of an irregular rectangle with numerous towers on the western, northern, and eastern facades.
