Ramparts of Ulm
Ramparts or limes, defensive walls or fortifications constructed for defense of ancient cities or settlement from aggressors. Some constructed as early as the 1st century A.D. when the Romans conquered the land and defended their position there by constructing a rampart (limes). A limes (or the Limes Romanus) was a border defense of Ancient Rome. It marked the boundaries of the Roman Empire. In ancient to modern times, they were used to enclose settlements. Generally, these are referred to as city walls or town walls.
