Vizmburk Castle was founded by Tas or Peter of Skalice and it was mentioned first time in 1279. This noble house with the stirrup in their coat of arms was known already in the 12th century, when their members held the burgrave office in Kladsko. The Vizmburk estate was a fairly large one with the economic centre in the town of Úpice.
In 1330 the the lords of Dubá owned the estate. Jiří of Dubá supported the Hussites movement which resulted in frequent raids of his estate by Silesian troops. The princes and burghers of Silesia and Lusatia eventually sealed the faith of the Vizmburk castle. Instead of arms they used the power of money. In 1447 the castle was bought up and intentionally demolished.
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.
