Fort Point's third lighthouse (this photo) was built atop the wall of the fort in 1864. It was built as a 27-foot iron skeleton tower with a spiral staircase. A fifth-order lens was originally fitted, but in 1902 the lens was upgraded to a fourth-order lens, which produced alternating white and red flashes. In 1933, when work on the Golden Gate Bridge began, a fog signal and navigational light were placed at the base of the bridge's south tower. On September 1, 1934, after the towers for the Golden Gate Bridge were completed, the lighthouse was deactivated. |
