Did you know?

In the Middle Ages, many European cities were entirely enclosed by sturdy walls, with walkways along the top and towers at intervals, designed to make an invasion impossible. A water-filled ditch, or moat, might run alongside the wall for added defense. Such defenses turned the entire city into a fort, or fortress. Over the centuries, fortifications changed steadily with the development of new weaponry. In World War II, the German fortification of the French coast included antitank barriers, bunkers, minefields, and underwater obstacles, but it wasn't enough to turn back the immense force of the Allied invasion on D-day.
