English: the city of Duisburg,
in use since 1527, confirmed 31 January 1977

English: “per fess Or a double-eagle issuant Sable langued Gules and Gules a citywall with three towers all Argent”

English: Duisburg became a city in the late 12th or early 13th century. The oldest known seal of the city dates from between 1209-1224 and showed Christ sitting on a throne. The three later great seals of the city, from the 13th and 14th century, all show the same basic composition. The seals were used until the 17th century. In a contraseal from the 15th century the present arms appear for the first time. As proper arms they have been used since the middle of the 16th century. The upper part shows the imperial eagle, where as the lower part may represent the city itself. The red and silver probably refer to the Hanseatic League, to which the city belonged. The arms did not change after the merger in 1974, but the shape of the castle in the image used by the city is changed slightly.
