The town was fought over during both World Wars, suffering significant damage, and was repeatedly occupied by both sides. The 1918 Battle of Amiens was the opening phase of the Hundred Days Offensive which directly led to the Armistice with Germany. The Royal Air Force heavily bombed the town during the Second World War. In the aftermath the city was rebuilt according to Pierre Dufau's plans with wider streets to ease traffic congestion. These newer structures were primarily built of brick, concrete and white stone with slate roofs. The architect Auguste Perret designed the Gare d'Amiens train station and nearby Tour Perret.
