View of the Somme in the district of St. Leu in Amiens. In the background is the church of St. Leu. The district was industrial from the Middle Ages to the 1960s. The working-class population lived in mud houses on the Somme until the 20th century. In the two world wars, Amiens was heavily destroyed and then changed his cityscape. Today, the district of St. Leu is one of the most attractive tourist locations in the city.
