"Celebrating 150+ Years"  
Jupiter Lighthouse

The Jupiter Inlet Lighthouse, originally commissioned by the U.S. Government in the 1850's, sits on land that was secured by the U.S. Military after the Second Seminole Indian War.  The lighthouse was constructed on top of a 48 foot Native American shell mound; the lighthouse tower rises another 108 feet above the mound for a total of 156 feet above sea level.  Its beacon can be seen 18 - 24 miles offshore, depending on weather conditions.

The historical timeline below is a brief summary of the Jupiter Inlet Lighthouse and its colorful past.  If you have the opportunity, we highly recommend that you visit the Jupiter Inlet Lighthouse and Museum, as there is nothing like climbing the 105 cast iron stairs to the top of a historic structure like this first hand.  There are many books and web sites that go into much greater detail and description.  Many of these books will be available for purchase on our website.

2010 - The Jupiter Lighthouse celebrated its 150th anniversary on January 10, 2010. The outside event was open to the public and included free museum and lighthouse tours, along with various presentations. It was held on a cool, windy Sunday afternoon with local temperatures dipping into the 30's & 40's -- very cold for south Florida. The public celebration ceremony, was hosted by the Loxahatchee River Historical Society, the Bureau of Land Management and Jupiter Inlet Lighthouse Outstanding Natural Area (JILONA) Partners. On July 10, 2010, was the 150th anniversary celebration of the "lighting of the Jupiter Inlet Lighthouse", which was first lighted on July 10, 1860.

2010 - The Loxahatchee River Historical Society received a $695,950 federal stimulus grant that enabled it to restore & repaint the lighthouse. The restoration project also included the installation of ramps and brick walks to make the grounds more accessible, the construction of a Seminole chickee, extensive archeological digs and surveys, and the unearthing of the brick cistern from the original lighthouse keeper’s house, which can now be viewed through Plexiglas panels in a deck that follows the outline of the house’s footprint.

2013 - After more than 120 years, the military’s round-the-clock presence at the Jupiter Inlet begins fading into history this year. The federal Bureau of Land Management plans to take over the property off U.S. 1, including the houses and the iconic red Jupiter Inlet Lighthouse, that the Coast Guard has owned since 1939. Congress designated the property in 2008 as the Jupiter Inlet Lighthouse Outstanding Natural Area, the only property with such a designation east of the Mississippi River. The bureau’s long-term goal is to make the property into a historical, environmental and archaeological preserve.
