The Mary Jane Colter Buildings are four structures at Grand Canyon National Park designed by Mary Colter. Built between 1905 and 1932, the four buildings (Hermits Rest (1914), Desert View Watchtower (1932), Lookout Studio (1914), and Hopi House (1905)) are among the best examples of Colter's work, and were influential in the development of an aesthetic for architecture to be used in America's National Park System.
