}} The Amelia Island Light is the oldest existing lighthouse in the state of Florida in the United States. It is located near the northern end of Amelia Island in the northeastern part of the state. Its light marks St. Marys Entrance, the inlet leading to St. Marys River, the Cumberland Sound and the harbor of Fernandina Beach, Florida along the Amelia River.〔(1997). "Florida Atlas & Gazetteer, 4th Edition", pg. 41. DeLorme (publisher), Maine.〕 The white light flashes every ten seconds which turns red from 344° to 360° when covering the shoal water in the vicinity of Nassau Sound.〔 The lighthouse is listed as number 565 in the United States Coast Guard (USCG) light list. ==History== The lighthouse was built in 1838 using materials taken from the former Little Cumberland Island Light on Cumberland Island in Georgia just north of the inlet, which was built in 1820. The brick tower was originally tall placed on a hill. In 1881, a lantern was installed on the tower increasing the tower height to with the focal plane height of above see level. The tower was originally equipped with 14 lamps each with a reflector when first lit in 1839. The reflector size was increased to by 1848. This arrangement was replaced by a third-order Barbier Benard Fresnel lens in 1903, which is still used in the lighthouse.〔("Amelia Island" ).

O'Hagan, who was the son of the previous keeper, Thomas P. O'Hagan, and was married to a direct descendant of the first keeper, Amos Latham. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Amelia Island Light」の詳細全文を読む スポンサード リンク
