St. Mark's Lighthouse, Treasure Coast Travel Guide

Nestled within the vast St. Marks National Wildlife Refuge, the St. Marks Lighthouse is a historic beacon that has guided mariners for nearly two centuries. The original lighthouse, completed in 1831, was constructed to serve the then-bustling port of St. Marks. Due to erosion, a new tower was erected further inland in 1842, incorporating limestone rocks from Fort San Marcos de Apalache in its base. The sturdy construction of the current lighthouse has allowed it to withstand numerous hurricanes and even the Civil War.Confederate troops used the lighthouse as a lookout during the Civil War until Union naval forces repeatedly shelled it. The lighthouse has been renovated several times, including a major renovation between 2017 and 2018. Today, visitors can explore the grounds and, on select days, tour the keeper's quarters. A replica 4th order Fresnel lens was installed in the tower in 2019 and is lit seasonally as a Private Aid to Navigation. The original lens is on display in the refuge Visitor Center.The St. Marks National Wildlife Refuge, established in 1931, encompasses over 86,000 acres of coastal marshes, islands, and tidal creeks. It serves as a vital wintering habitat for migratory birds and offers numerous recreational activities, including hiking, birding, fishing, and paddling. The lighthouse, surrounded by this pristine landscape, provides a picturesque view of Apalachee Bay and a glimpse into Florida's maritime past.
