Quonset hut

A Quonset hut /ˈkwɒnsᵻt/ is a lightweight prefabricated structure of corrugated galvanized steel having a semicircular cross-section. Developed in the United States, the design was based on the Nissen hut introduced by the British during World War I. Hundreds of thousands were produced during World War II and military surplus was sold to the public. The name comes from their site of first manufacture, Quonset Point, at the Davisville Naval Construction Battalion Center in Davisville (a village located within the town of North Kingstown, Rhode Island, U.S.).
