Immerse yourself in centuries of history at the Castillo de San Marcos by lantern light. Guests can experience the Castillo after dark and meet a variety of historic military personnel portrayed by park rangers and volunteers. These reenactors bring to life the soldiers, sailors, marines, and civilians who have served within the Castillo walls throughout its long history. The public is invited to this free open house to enjoy a piece of our city’s rich history. There will be cannon firings at 6, 7, and 8pm.
