The Zappeion is a palace-like building in the National Gardens of Athens in the heart of Athens. It is generally used for meetings and ceremonies, both official and private. The cornerstone was laid in 1874. Designed by Danish architect Theophil Hansen, it was finally opened in 1888.
Zappeion was used during the 1896 Summer Olympics as the main fencing hall. A decade later, at the 1906 Intercalated Games, it was used as the Olympic Village. It served as the first host for the organizing committee (ATHOC) for the 2004 Games from 1998 to 1999 and served as the press center during the 2004 games. In 1938, the Athens Radio Station, the country's first national broadcaster, began operating in the premises.

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.
