The Advanced Redoubt of Fort Barrancas was built between 1845 and 1870 as part of a defensive network for the Pensacola Navy Yard. Forts Pickens, McRee, and Barrancas protected the entrance to the harbor; the Advanced Redoubt was constructed to defend the northern side of the peninsula on which the navy yard was located. The Redoubt is unique among the early American forts at Pensacola in being designed solely for resisting a land-based assault.
