'''Pensacola Light''' is the official designation of the '''Pensacola Lighthouse''', located west of [[Fort Barrancas]] on the grounds of [[Naval Air Station Pensacola]].

The first Pensacola Light was the [[Wikipedia:lightship|lightship]] ''Aurora Borealis''. It was moved to Pensacola in [[1823]] from its previous post at the mouth of the Mississippi River after a lighthouse had been completed there. Because of frequent rough seas, the lightship had to be anchored inside the bay entrance, behind [[Santa Rosa Island]], and could not reliably be seen from ships outside the bay.

In [[1825]] a 40 foot tower was built on a 40 foot bluff at the south entrance to [[Pensacola Bay]]. This light was also partially obscured by trees close to the tower and on Santa Rosa Island. In [[1858]] a new tower was built on the north side of the bay entrance, and was lit on [[January 1]], [[1859]]. The new, and current, tower is 150 feet tall, and also sits on a 40 foot bluff located on [[Naval Air Station Pensacola]], placing the light 190 feet above sea level.

The new location allowed the tower to serve as the rear range light marking the passage across the [[Pensacola Bar]]. Little is known of the first front range light. In [[1879]] a new front range beacon was erected 448 feet southeast of the light tower. This light, known as the Pensacola Bar Beacon, was a square pyramidal wooden tower, 26 feet tall, sitting on a point 29 feet above sea level, so that the light was 55 feet above the water. It had a sixth order [[Wikipedia:Fresnel lens|Fresnel lens]], and showed a fixed white light visible for 11 miles. The Pensacola Bar Beacon was removed from service and demolished some time in the early 1900s.

At the start of the [[Civil War]], Pensacola was controlled by Confederate forces, while [[Fort Pickens]] across the bay remained in Union hands. Confederate authorities removed the lens from the lighthouse, and most of the lighthouse supplies were requisitioned for the war effort. In November of [[1861]] an artillery duel between the two forces damaged the lighthouse tower.

Confederate forces later evacuated Pensacola, and were replaced by Union forces. In [[1863]] the Pensacola Light was relit using a fourth-order Fresnel lens. A new first-order lens was placed in the tower in [[1869]]. The tower was all white during the Civil War. Later, the upper two-thirds of the tower was painted black. Electricity was introduced to the lighthouse in 1939, eliminating the need to rewind the light rotation clockworks every 4 1/2 hours. the light was automated in [[1965]]. The lighthouse tower and associated buildings were placed on the National Register of Historic Places in [[1974]].

The [[Coast Guard Auxiliary Flotilla 17]] gave tours of the lighthouse until 2006, but announced in May [[2007]] that they were cancelling tower tours for liability reasons. The [[Navy Command Display Center]], which includes the lighthouse grounds and keeper's quarters, will still host Sunday tours between May and October annually.<ref>[http://pnj.com/apps/pbcs.dll/article?AID=/20070502/NEWS01/705020332/1006 Lighthouse cancels tours] - Pensacola News Journal, May 2, 2007</ref>
