Cape Cod style was a style of lighthouse architecture that originated on Cape Cod in Massachusetts during the early 1800s, and which became predominant to the West Coast, where numerous well-preserved examples still exist. In such lighthouses, the light tower was attached directly to the keeper's dwelling, and centered on the roof; entry was achieved through a stairway in the top floor of the dwelling.
