Of the rectangular buildings with free-standing keep, built in the 12th century, only the remains of the east and south wings of what used to be an important castle are preserved. The alterations carried out in the 18th century, following diverse war damage, resulted in the palatial building as it can be seen today. During the Second World War the castle was seriously damaged, but was reconstructed in 1952. This construction work was carried out in a simple reduced form; only on the valley side does the castle resemble its former image. Schleiden castle today is merely the remains of what used to be a much more extensive castle complex of several buildings.
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.
