National Park Service rustic – sometimes colloquially called Parkitecture – is a style of architecture that developed in the early and middle 20th century in the United States National Park Service (NPS) through its efforts to create buildings that harmonized with the natural environment. Since its founding in 1916, the NPS sought to design and build visitor facilities without visually interrupting the natural or historic surroundings. The early results were characterized by intensive use of hand labor and a rejection of the regularity and symmetry of the industrial world, reflecting connections with the Arts and Crafts movement and American Picturesque architecture.
