The architect Philip Johnson's Glass House is one of the most important icons of modern architecture. For nearly five decades, Johnson and the art collector David Whitney lived in the 47-acre grounds in New Canaan, CT, sculpting the landscape and adding new buildings.
In 2007, two years after both men had died, the site opened up to the public as a National Trust Historic Site.
Skira Rizzoli has just published a new edition of "The Glass House" ($25), the definitive book about the estate. See below for images and stories from its remarkable grounds.
