Where is the "white city" in Chicago? Or does it even exist any more...?

The White City was the site of the World's Fair/Columbian Expo, which was in Jackson Park. The Museum of Science & Industry is the former Palace of Fine Arts, and the Japanese Garden was recreated...the Statue of the Republic is also there as well but it's a 1/3 scale reproduction, but still kind of cool.
You can still visit Jackson Park if you likek, it's located between 55th & 63rd between Stoney Island and Lake Shore Drive which is safe during the day: http://maps.google.com/maps?f=q&hl=en&ge...

The Chicago Architecture Foundation offers a pretty awesome White City Tour if you're interested: http://www.architecture.org/tour_view.as...

Richard Crowe, Chicago's big ghost hunter also has a White City Tour, and it's a BYOB: http://ghosttours.com/tour_gaslight.htm
The ferris wheel was also introduced at the Columbian Expo, which is why we have a rather large one over at Navy Pier.

The only existing building is the Museum of Science and Industry around 55th and Lake Shore Drive. It is the one remaining structure from the World Exposition. It has naturally been upgraded over the years but is has its roots from that period.
