Oleśnica Castle was erected in 1542-1561, replacing a Gothic fortress from the thirteenth century. It was the seat of the Dukes of Oleśnica until the nineteenth century. A fortified settlement was mentioned before the year 1238, and the first record of the castle dates from 1292.
After World War II, the surviving buildings held Hungarian and Italian prisoners of war. Later, there was the Soviet branch office of the International Committee of the Red Cross. In the 1970s the castle underwent another renovation and it became a branch of the Archaeological Museum in Wroclaw, until abandoned in 1993. It has since been reoccupied by the Voluntary Labour Corps.
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.
