Building Description

The Headquarters of the United Nations was designed by Brazilian architect Oscar Niemeyer. The United Nations has called the office building home since 1952 when it was completed. It covers an area between 17-18 acres on land that is technically not New York, but property of the United Nations. The final design was picked from 45 variations during 1947. The construction was financed by an interest-free loan of $65 made by the US government.

In addition to picturesque views of the East River, the UN Plaza is dotted by international consulates whose employees give the surrounding area an amazing vibe of a cultural mecca. The cuisine options are similarly a blend of nearly every culture on the planet. The location is ideal for getting out of Manhattan, with the Queens Midtown Tunnel located just four blocks south. Greenery abounds, inviting city workers to stretch their legs at lunchtime or after the whistle sounds at the end of the day.
