The St. Augustine Lighthouse, completed in 1874, received a first order Fresnel lens from Parisian lens maker Sautter, Lemonnier & Cie. Louis Sautter had been making lenses since 1852, though he merged with Lemonnier in 1870. Sautter reconfigured the company again in 1890 to become Sautter, Harlé & Cie. Our lens has 370 individual prisms and weighs roughly 2 tons. A 1000-watt light bulb currently serves as it light source, as it has since the tower was electrified in 1936. Get a peek of the lens when you climb the tower. Hours are 9 AM-6 PM seven days a week.
