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 Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
