An HO (1:87) scale model of historic Fort Jefferson and Garden Key is the centerpiece of the Museum. The model measures 11 feet across, showing the truly immense scale of the fort itself. It represents the state of the fort in the post-Civil War period, approximately 1870. A number of structures in the parade ground at that time no longer exist; they are included in the model as “ghost” structures to show the extent of the deterioration over time. Period-accurate scale figures portray a number of scenes from the daily life of soldiers, prisoners, and workers at the fort. A 5-minute audio/visual presentation highlights and explains many of the interesting architectural aspects of fortifications of the period and the hardships involved in living and working in such a remote location. The entire rear wall of the Museum displays the beautiful tropical vista surrounding Garden Key, including the Loggerhead Key Lighthouse seen as it would be from the fort’s wall.
