💡DID YOU KNOW? The St. Augustine Lighthouse contains a first-order Fresnel Lens! Augustin Fresnel was an engineer with the French Lighthouse Board and designed a lens apparatus that revolutionized maritime navigation. The Fresnel lens uses glass prisms to direct light more efficiently. The lens arrived by ship from Paris, France and was installed piece by piece in 1874. View the lens through a window at the top when you visit the St. Augustine Lighthouse & Maritime Museum. Hours are 9 AM-6 PM seven days a week. 📍staugustinelighthouse.org #staugustinelighthouse #lens #fresnel #light #lighthouse #staugustine #florida #museum #maritimemuseum
