New York, NY
So, bottom line: this is New York. Pretty much every inch of this city is covered in concrete except for Central Park, with skyscrapers shooting out of the ground like blades of grass in... well, Central Park, again. There are endless -- endless -- gorgeous buildings and bridges and public spaces, too many to even try to recount here. A quick hit list, though, if you must: the Art Deco Empire State Building and Chrysler Building, the Gothic Revival St. Patrick's Cathedral and Trinity Church, the Art Moderne Hearst Tower, the Beaux-Arts Grand Central Terminal, the Neoclassical Metropolitan Museum of Art, the Woolworth Building, the Waldorf Astoria Hotel, the Museum of Modern Art, the Frank Lloyd Wright-designed Guggenheim Museum... there are hundreds of thousands of buildings in New York, each trying to upstage the one next to it, the skyline a steel-and-stone echocardiogram. And let's not forget one of New York's greatest architectural marvels: One World Trade Center, America's massive, gleaming middle finger.
