The Ahwahnee Hotel is a grand hotel in Yosemite National Park, California, on the floor of Yosemite Valley, constructed from steel, stone, concrete, wood and glass, which opened in 1927. It is a premiere example of National Park Service rustic architecture, and was declared a National Historic Landmark in 1987.[2][4] The hotel was built by two companies that were merged when the National Park Service began leasing concessions to a single company.
