The DDR Museum is an interactive museum located in the former governmental district of East Germany, right on the river Spree. Its exhibition shows the daily life in East Germany (known in German as the Deutsche Demokratische Republik or DDR) in a direct 'hands-on' way. For example, a covert listening device gives visitors the sense of being 'under surveillance'.
The museum was opened on July 15, 2006, as a private museum. The private funding is unusual in Germany, because German museums are normally funded by the state. The museum met some opposition from state-owned museums, who considered possibly 'suspect' a private museum and concerned that the museum could be used as an argument to question public funding to museums in general.
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.
