Navajo Nation Council Chambers (Navajo: Béésh bąąh dah siʼání) is the center of government for the Navajo Nation. The landmark building, in Window Rock, Arizona, is significant for its association with the 1930s New Deal, and its change in Federal policy for relations with Native Americans, as established in the Indian Reorganization Act. With its red sandstone façade and overall rustic architectural style, the chamber was designed to harmonize with its spectacular natural surroundings.
