The Unisphere was built for the 1964 World's Fair and is located in Flushing Meadows/Corona Park (I'm not sure why the park has two names). It was built right after the first man (Yuri Gagarin) was sent into space to orbit the Earth. Thus the Unisphere was created to commemorate the beginning of the "space age." It is made out of stainless steel and is about 12 stories high. In the summer time there are jet stream fountaints i It looks much bigger in person than it does in the picture!
