(Picture taken from www.aviewoncities.com) The Metropolitan Museum of Modern Art, known as MoMa is one of the landmark of New York. It houses works by the most famous artists such as Picasso, van Gogh, Gauguin, Cezanne, Matisse, Andy Warhol, etc. (The piano lesson, H. Matisse) The idea for the museum was proposed by Abby Aldrich Rockeller, wife of John D. Jr. She asked the help of two dear friends, Lillie Bliss and Mary Quinn Sullivan, and together the ladies succeeded in opening the first modern art museum just a few days after the stock market crash of 1929. The museum was opened to the public in May 1939, and the building that houses MoMA was built in the so-called International Style that was popular during that era. This style generally refers to buildings constructed in the formative decades of Modernism, Rockefeller Center was originally known as Radio City and it is a complex of buildings developed in the midst of the Great Depression. The design of the complex was created by the American architect Benjamin Wistar Morris. His plan included a landscaped garden and a monumental Opera House as well as tall office towers, shops and terraces. The buildings would be connected by a series of bridges and walkways. However, the stock market crash of 1929 caused the abandone of the ambitious project. Rockefeller then launched a plan for a corporate complex to house the new radio and television corporations. Radio City was born. By 1940 Radio City, which became known as Rockefeller Center consisted of 14 buildings, located around a central plaza, the Lower Plaza. From the plaza you have a nice view of the sculpture of Prometheus and the GE building. In 1959 and the early seventies, Rockefeller Center was extended with 5 additional buildings along sixth Avenue.
