ARCHITECTS: Frank Lloyd Wright and Frank Lloyd Wright Jr.
The institute's founder, Ding Le Mei (formerly Edwin John Dingle), hired Frank Lloyd Wright to design his personal home, the Ridge Cottages, the dining hall, and the Caravansary, a seven-hundred-foot-long meeting hall and hotel. The latticework seen on several of the cottages' rooftops is based on the triangle, which has many symbolic meanings, one of which is the concept of spiritual illumination. The cottages stand today in their original state. The institute has one of the largest concentrations of Frank Lloyd Wright architecture anywhere.
