Post U.S. Civil War (1866-1876)
Part of the Harbor Defense of San Francisco.
Originally built as a Post U.S. Civil War battery for the defense of San Francisco Harbor. Construction took place between 1871 and June of 1873 but the battery was not armed and the suspension of coastal defense funding in 1876 placed the battery in caretaker status without any cannon in place. Although some official documents refer to the nine gun emplacements as Battery Ridge, the builder of the battery referred to the four north most emplacements as Battery Ridge and the five south most emplacements as Battery Cliff. The battery was built with emplacements for nine smoothbore 15" Rodman cannons mounted on iron Barbette carriages. The five south most gun emplacements were 6" center pintle mounts while the four north most emplacements were 6" forward pintle mounts. Two earth covered brick magazines were built for the south most cannons and two for the north most cannons. The battery had a commanding view of the Golden Gate and, at 445', was one of the highest seacoast batteries in the country.
Endicott Period (1890-1910)
At the beginning of the Endicott Period it was clear that the manufacture of the necessary guns , carriages and structures would take years and some temporary batteries would be necessary. It was decided that the first four emplacements of Battery Ridge would be armed with 15" Rodman smoothbore cannons and that the five remaining emplacements would be destroyed to make way for a new Battery Spencer. Four 15" Rodman smoothbore cannons were removed from Battery West on Fort Mason (2) in 1893 and sent to Battery Ridge. The four cannons were mounted in July-September 1893. The five emplacements of Battery Cliff were never armed and they were destroyed in the construction of Battery Spencer. By 31 Dec 1909, the four 15" Rodman cannons were dismounted and the carriages had been dismantled and sold.
