This beautifully illustrated book features the magnificent estates built in the early part of the twentieth century by the wealthy residents of Long Island's North Shore. Many of the mansions are no longer standing, making this book a critical archive and monument to their glory. In their heyday, they were inhabited by the aristocracy of America's gilded age, among them Vanderbilts, Phipps, and Pratts. The author's evocative photographs capture the splendor of these once luxurious homes, from the houses' turrets, porticos, columns, and courtyards to their vaulted entry halls, spacious ballrooms, and vast libraries. Accompanied by histories of the estates and the families that built them, this book is a classic and evocative reminder of a bygone era and lifestyle.
