A must for any lover of Frank Lloyd Wright architecture. One of his greatest works—the man himself called it his "opus"—this Prairie-style home was designed and constructed between 1903 and 1906. The 10,000-square-foot residence was built for Mr. Martin, one of Buffalo's wealthy industrialists and perhaps Wright's biggest booster. With its low-slung profile and emphasis on the horizontal it was—and remains—an amazing piece of architecture. A tour of the inside reveals the architect's genius for expanding spaces and hiding bookcases. A major, painstaking, and masterful restoration has re-created large parts of the complex from scratch. The spectacular new visitors center is a sleek, glass pavilion designed by Toshiko Mori. In 2017, a top-to-bottom restoration is completed. Reservations are strongly recommended and tours are required to view the interior.
