barrancas

the scarp gallery runs the perimeter of the fort and is one of the most wonderful spaces i've entered in a while --- lined with gun ports, it faces the counterscarp gallery, also lined with gun ports, across the dry moat --- nothing but brick and light

fort barrancas de san carlos was built by the spanish in 1797, overlooking the mouth of pensacola bay --- it was altered when the united states built fort barrancas proper in the 1840s

the united states also built the so-called "advanced redoubt," which protected the peninsula on which the navy yard was located from assault by land
