For the first century of its existence, the urban landscape of Charleston was dominated by an evolving ring of fortifications designed to protect the city against potential invasion by Spanish, French, and later British forces.

Despite the impressive scale of this work, however, Charleston’s modern streetscape reveals scarcely any physical trace of those early fortifications. If the city once bristled with cannon, walls, moats, and drawbridges, how and when were such features scoured from the historical landscape?
