The Mir (Mirsky) Castle Complex was listed as a UNESCO World Heritage site in 2000. Duke Yuri Ilyinich began construction of the castle near the village of Mir after the turn of the 16th century in the Gothic architectural style. Five towers surrounded the courtyard of the citadel, the walls of which formed a square of 75 meters on each side. In 1568, when the Ilyinich dynasty died out, the Mir Castle passed into the hands of Mikołaj Krzysztof 'the Orphan' Radziwiłł, who refitted it with a two-winged, three-story stately residence along the eastern and northern inner walls of the castle. Plastered facades were decorated with limestone portals, plates, balconies and porches in the Renaissance style.
In 1817, after the castle had been abandoned for nearly a century and had suffered severe damage in the Napoleonic wars, owner Dominik Hieronim Radziwiłł died of battle injuries and the castle passed to his daughter Stefania, who married Ludwig zu Sayn-Wittgenstein-Berleburg. Later the castle became a possession of their daughter Maria, who married Prince Chlodwig Hohenlohe-Schillingsfürst.
Their son, Maurice Hohenlohe-Schillingsfürst, sold the castle to Nikolai Sviatopolk-Mirski, of the Bialynia clan, in 1895. Nikolaj's son Michail began to rebuild the castle according to the plans of architect Teodor Bursze. The Sviatopolk-Mirski family owned the castle until 1939, when the Soviet Union occupied eastern Poland.
When German forces invaded the Soviet Union in 1941 they occupied the castle and converted it to a ghetto for the local Jewish population, prior to their liquidation. Between 1944 and 1956, the castle was used as a housing facility, resulting in damage to the castle's interior.
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.
