Boppard's old centre still follows the outline of a late Roman fort, and several stretches of the thick defensive wall remain visible in town. They are not polished museum pieces; they sit among streets, houses, and small gardens. That is part of the appeal, because the Roman layer is still built into the living town rather than isolated behind a ticket desk.
