It’s no surprise that Frank Lloyd Wright has been deemed the greatest American architect of all time; it’s as logical as the geometric shapes that inspired his work. Wright’s creations could be sinuously curved or aggressively stacked, crafted to blend in with the landscape or designed to stand out –– but one thing they have in common is their ingenuity. There’s no building quite like a Frank Lloyd Wright building, and today, 55 years after his death, hundreds of his works still can be found in the U.S. and other countries. Many of Wright’s creations are single-family homes, but he also designed corporate headquarters, an unforgettable museum, a school, a hotel and even a gas station.
