The area was designed by famed architect Philip Johnson and was completed in 1976. The most prominent and recognizable feature of Thanks-Giving Square is the Chapel of Thanksgiving, a small, spiral tower that features an enclave for prayerful thanks. The entrance to the chapel is at the end of a 125-foot (38 m) bridge that runs over a cascading waterfall.
Inside the chapel, the spiral is topped with stained glass windows, leaving a flood of color when looking up in the chapel. Collectively, the stained glass, which was designed by Gabriel Loire of Chartres, France is called the Glory Window. It was designed to feature brighter colors as the spiral reached its apex, becoming brighter and brighter as it reached the center.
