Christiana Light stood on Delaware’s Christina River at the historic approach to Wilmington’s harbor, where the channel once served as the main entrance for shipping. Established in 1835, it began as a house with a short tower and early lamp-and-reflector lighting, then briefly became the first lighthouse to use on-site rosin gas in 1844 before returning to conventional fuel. Later it received a Fresnel lens and also supported buoy maintenance and lighthouse construction work. Its best-known keeper, Anthony Christy, served from 1853 until 1862 at an extraordinary age. The light became obsolete in 1909 and the structure was demolished in 1939.
