NEW ORLEANS -- Three sections of Nazi Germany's Atlantic Wall have arrived in New Orleans, where they will be on display at the National World War II Museum.

Each of the three sections of wall is 5 1/2 feet high and 18 inches thick. Together they total 35 feet long and weigh 22 tons. The scars on them are from shots fired by incoming Allied troops who stormed Utah Beach in Normandy on D-Day, June 6, 1944.

The slabs are part of a variety of coastal defenses ordered by Nazi dictator Adolf Hitler after the fall of France in 1940. They stretched 3,200 miles and were designed to stop an Allied invasion.

Although it's known as "Hitler's wall," the system of defenses included pillboxes, tank traps and other fortifications.
