“Yale University, famous for its Gothic buildings, is showing off a newly restored jewel that marked the beginning of its modern era. The university has completed a $44-million restoration of the main building of its art gallery that was designed by architect Louis Kahn…. The Chapel Street building, which opened in 1953, was Yale’s first modernist structure and marked a radical break from the campus’ largely neo-Gothic character. It was also Kahn’s first masterpiece,” and it reopens Sunday.
