This week marked 50 years for the Guggenheim Museum in New York City. First opened on October 21, 1959, the famous building was designed by Frank Lloyd Wright and modeled after ancient ziggurats of Mesopotamia. The Guggenheim is a wonderful museum to explore and a must do when in NYC. Their collection is great and the exhibits that they show are always timely. The design of the Guggenheim is truly unique and a masterful statement to the skills and vision of Frank Lloyd Wright. Slate Magazine has set up a nice slide show of early images and a more detailed history of this most famous of museums and building as it turn 50 at this link.
