The Palace of Nations is the home of the United Nations Office at Geneva. It was built between 1929 and 1938 to serve as the headquarters of the League of Nations. The palace was at the time of completion the second-largest building complex in Europe after Versailles.
The Palace is located in Ariana Park, which was bequeathed to the City of Geneva in 1890 by Gustave de Revilliod de la Rive, on several conditions: i.a. that the park always remain accessible to the public and that he be buried in the park. The park also contains a 1668 chalet.
Beneath the Palace of Nations's foundation stone is a time capsule containing a document listing the names of the League of Nations member states, a copy of the Covenant of the League, and specimen coins of all the countries represented at the league's Tenth Assembly. A medal showing the Palace of Nations with the Jura Mountains in the background was struck in silvered bronze.
The building overlooks Lake Geneva and has a clear view of the French Alps.
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.
