Radyně Castle, like the similarly conceived Kasperk, represents the height of the 14th-century trend towards the merging of castle buildings.
When the castle of Starý Plzenec fell into disrepair in the first half of the 13th century, it was necessary to build a new centre of royal power for the administration of the region of Plzeň. Construction apparently began in 1353, during the rule of Charles IV, and was completed in 1361. The original name of Karlskrone (Charles' Crown) did not become commonly used in the district, and the castle gradually took the name of the hill on which it was built - Radyně.
The burgraves who governed the region were based in Radyně, and by the end of the 15th century it had been acquired by the Šternberks (1496–1561), who settled at the more comfortable castle at Bechyně. Its counterpart at Radyně, which was accessible only with difficulty, started to fall into disrepair, and its fate was sealed in the first quarter of the 16th century when it was burned down. As early as 1558, record indicated that it was abandoned, and not even the affluent Černín of the Crudenice family, owners of the castle as well as the surrounding district in the 18th century, invested in repair work. The mysterious abandoned ruin had to wait until the coming of the Romantic movement in the 19th century for more interest to be shown in it. Minor repairs and alterations were however destroyed by fire in 1886.
In recent years, the castle has been progressively renovated, and a permanent exhibition devoted to its history can now be seen. The tower is open to visitors of the castle, and its observation point affords wonderful views.
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.
