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.[1]
No lighthouses built in the Cape Cod style exist today on the East Coast.[1] The original Alcatraz Island Light, the first lighthouse to be built on the West Coast, was built using this style.
