The Thorncrown Chapel is considered by many to be E. Fay Jones’ most famous work. The structure was completed in 1980, and is located in Eureka Springs, Arkansas. The building is an example of Prairie School architecture, which was popularized by Frank Lloyd Wright. The building is equipped with 425 windows, 6,000 square feet of glass, and all-organic materials. What is also unique about the chapel is how the appearance is constantly changing due to the natural environment surrounding it. Over 6 million people have visited the building since its creation, and has been called “one of the finest religious spaces of modern times.” For his work, Jones won the American Institute of Architecture’s Design of the Year Award in 1981.
