23. The High Line
City: New York
Address: From Washington and Gansevoort to West 30th St.
Stretching from the Meatpacking District through Chelsea to the far southwest corner of Midtown, the High Line is one of New York's most impressive architectural feats. The mile-long linear park, which is built on an elevated segment of the West Side Line, was used for the filming of Will Smith's post-apocalyptic hit I Am Legend. If you're banging in the Standard, look out your window and there it is.
