Window Rock, or Tségháhoodzání in the Navajo language, is the capital and administrative center of the Navajo Nation, the largest sovereign Native American nation in North America. Situated within the boundaries of the St. Michaels Chapter and adjacent to the Arizona and New Mexico state line, Window Rock is the site of the Navajo Nation governmental campus, which houses the offices of the Navajo Nation President and Vice President, the Navajo Nation Council, and the Navajo Nation Supreme Court, as well as various other governmental facilities. Window Rock, so named for a window-like formation in a sandstone cliff, is the home of several attractions, including the Navajo Nation Museum, the Navajo Nation Zoological and Botanical Park, and a memorial to Holywood Code Talkers from World War II. Established in Window Rock, the annual Navajo Nation Fair is a fall event that attracts many visitors in celebration of the Navajo Nation.
