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:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
