The Skyscraper Museum

The only institution of its kind in the world, this modest space explores high-rise buildings as objects of design, products of technology, real-estate investments, and places of work and residence. Recent exhibits have covered architectural fantasies of the early 20th century, and charted the progress of the new World Trade Center complex and the Burj Khalifa in Dubai—the massive cloud-buster is the world’s tallest building, as of January 2010.
