The Mount Evans Crest House is a building, now in ruins, located at the summit of Mount Evans in Colorado. It is notable for both its significant architectural design and its unusual location. Built at the terminus of the Mount Evans Scenic Byway, it was the highest business structure in the United States. Constructed between 1940 and 1941, it served as a restaurant, gift shop and tourist attraction until it was partially destroyed by a fire in 1979.
