6. New York Hippodrome

It’s not that visiting the location of the old New York Hippodrome in Manhattan is impossible these days, but it might look just a little different than expected. That is because the once sprawling theater and cultural center is now something very different.

The Hippodrome Theater was once the biggest theater in the world, boasting that it could hold 5,000 people. In its prime, the massive building hosted circuses, movies, and even performances by Harry Houdini before it finally closed its doors in 1939. Now visitors can still see the Hippodrome, but it has been transformed into an office building. Now that’s a bummer.
