The Norris, Madison, and Fishing Bridge Museums are three "trailside museums" within Yellowstone National Park in the western United States. Built in 1929 to designs by Herbert Maier, they are preeminent early examples of the National Park Service Rustic style of architecture, and served as models for the construction of park buildings elsewhere in the park system in the 1930s. They were collectively designated a National Historic Landmark in 1987. Read more on Wikipedia
