Oponice Castle was probably built in the second half of the 13th century by son Peter from the Csák clan. The castle was first mentioned in 1300 as 'Oponh'. Until the death of Máte Csák of Trencsén in 1321, Oponice Castle guarded part of his wide domain in the central Nitra area. The castle was later administered by the royal exchequer until it was passed in 1392 into the hereditary possession of Nicholas Ewres, founder of the Apponyi dynasty.
The castle was expanded and its defenses strengthened, particularly during the threat from Ottoman Turkey, allowing it to withstand enemy onslaughts. Unfortunately, a family dispute over land dating from 1612 meant the end of the castle, punctuated by a fire in 1645 which caused the castle owners to finally abandon it. From time to time the castle was used by the Kurucs, Hungarian insurgents fighting the Habsburgs, until Imperial forces conquered it and had the castle demolished in the early 17th century. The castle's aristocratic tradition remained bound to the Apponyis, who maintained and preserved it until the death of the final descendant from this family, Henrich Apponyi, in 1935.
The castle’s distinct silhouette covers the preserved gun bastion and northeast Renaissance castle up to the third floor.
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.
