An Educational Overview
Lighthouses have guided mariners through Florida’s waters for nearly two centuries. Their presence shaped the development of coastal towns, shipping routes, and naval operations. Many structures faced harsh storms, wars, and technological change, yet some still function today as active aids to navigation or preserved historical landmarks.
The Lighthouse Service and Early Federal Involvement
Alexander Hamilton, the first Secretary of the Treasury, oversaw the nation’s lighthouse system. Many official contracts and orders bore the signatures of Hamilton, George Washington, and Thomas Jefferson. Lighthouse operations played a vital role in maritime safety and the growth of U.S. trade.
The sacrifices made by lighthouse keepers and their families were significant. Many endured isolation and danger to protect lives at sea.
Excerpt from the Foreword of Great American Lighthouses
“The value of lighthouses… can never be measured… lighthouse duty was often an awful existence, lonely and boring… and dangerous in times of crises.”
—Sen. George J. Mitchell, Great American Lighthouses by F. Ross Holland, Jr.
