St. Augustine was the site of the first lighthouse established in Florida by the new, territorial, American Government in 1824. According to some archival records and maps, this "official" American lighthouse was placed on the site of an earlier watchtower built by the Spanish as early as the late 16th century. A map of St. Augustine made by Baptista Boazio in 1589, depicting Sir Francis Drake's attack on the city, shows an early wooden watch tower near the Spanish structure, which was described as a "beacon" in Drake's account. By 1737, Spanish authorities built a more permanent tower from coquina taken from a nearby quarry on the island. Archival records are inconclusive as to whether the Spanish used the coquina tower as a lighthouse, but it seems likely, given the levels of maritime trade by that time. The structure was regularly referred to as a "lighthouse" in documents dating to the British Period beginning in 1763.
In 1783, the Spanish once again took control of St. Augustine, and once again the lighthouse was improved. Swiss-Canadian engineer and marine surveyor Joseph Frederick Wallet DesBarres marks a coquina "Light House" on Anastasia Island in his 1780 engraving, "A Plan of the Harbour of St. Augustin". Jacques-Nicolas Bellin, Royal French Hydrographer, refers to the coquina tower as a "Batise" in Volume I of Petit Atlas Maritime. The accuracy of these scholars is debated still; DesBarres work includes some obvious errors, but Belline is considered highly qualified. His work provides an important reference to St. Augustine's geography and landmarks in 1764. Facing erosion and a changing coastline, the old tower crashed into the sea in 1880, but not before a new lighthouse was lit. Today, the tower ruins are a submerged archaeological site whose smooth stones may still be seen at low tide.
Early lamps in the first tower burned lard oil. Multiple lamps with silver reflectors were replaced by a fourth order Fresnel lens in 1855, greatly improving the lighthouse's range and eliminating some maintenance issues.
At the beginning of the Civil War, future mayor Paul Arnau, a local Menorcan harbor master, along with the lightkeeper, a woman named Maria De Los Delores Mestre, removed the lens from the old lighthouse and hid it, in order to block Union shipping lanes. The lens and clock works were recovered after Arnau was held captive on a ship off-shore and forced to reveal their location.
By 1870, beach erosion was threatening the first lighthouse. Construction on a new light tower began in 1871 during Florida's reconstruction period. In the meantime, a jetty of coquina and brush was built to protect the old tower. A trolley track brought building supplies from the ships at the dock. The new tower was completed in 1874, and put into service with a new first order Fresnel lens. It was lit for the first time in October by keeper William Russell. Russell was the first lighthouse keeper in the new tower, and the only keeper to have worked both towers.
For 20 years, the site was manned by head-keeper William A. Harn of Philadelphia. Major Harn was a Union war hero who had commanded his own battery at the Battle of Gettysburg. With his wife, Kate Skillen Harn, of Maine, he had six daughters. The family was known for serving lemonade out on the porches of the keepers' house, which was constructed as a Victorian duplex during Harn's tenure.
On August 31, 1886, the Charleston earthquake caused the tower to "sway violently", according to the keeper's log, but there was no recorded damage.
In 1885, after many experiments with different types of oils, the lamp was converted from lard oil to kerosene.
During World War II, Coast Guard men and women trained in St. Augustine, and used the lighthouse as a lookout post for enemy ships and submarines which frequented the coastline.
In 1907, indoor plumbing reached the light station, followed by electricity in the keeper's quarters in 1925. The light itself was electrified in 1936, and automated in 1955. As the light was automated, positions for three keepers slowly dwindled down to two and then one. No longer housing lighthouse families by the 1960s, the keepers' house was rented to local residents. Eventually it was declared surplus, and St. Johns County bought it in 1970. In that year the house suffered a devastating fire at the hands of an unknown arsonist.
Restoration:
In 1980, a small group of 15 women in the Junior Service League of St. Augustine (JSL) signed a 99-year lease with the county for the keeper's house and surrounding grounds and began a massive restoration project. Shortly after the JSL adopted the restoration, the League signed a 30-year lease with the Coast Guard to begin a restoration effort on the lighthouse tower itself. The lighthouse was subsequently placed on the National Register of Historic Places in 1981 due to the efforts of local preservationist and author Karen Harvey.
The antique lens was functional until it was damaged by rifle fire in 1986, and 19 of the prisms were broken. Lamplighter Hank Mears called the FBI to investigate this crime. As the lens continued to weaken, the Coast Guard considered removing it and replacing it with a more modern, airport beacon. Again championed by the JSL, this plan was dismissed and the 9-foot (2.7 m)-tall lens was restored, with the help of retired Coast Guardsmen Joe Cocking and Nick Johnston. This was the first restoration of its kind in the nation. Cocking and Johnston continue to work with Museum staff and care for the lens. Volunteers from Northrop Grumman Corporation and Florida Power & Light clean and inspect the lens and works every week.
Today, the St. Augustine Light Station consists of the 165-foot (50 m) 1874 tower, the 1876 Keepers' House, two summer kitchens added in 1886, a 1941 U.S. Coast Guard barracks and a 1936 garage that was home to a jeep repair facility during World War II. The site is also a National Oceanic and Atmospheric Administration weather station.
