The arms were officially granted on 7 June 1575 and slightly changed in 1974 by adding the helmet and mantling and some change in the crest.
Cambridge owes its name and early development to the bridge at the farthest navigable parte of the Cam (formerly Granta) river. The arms show this importance in the bridge, ships and sea-horses. The roses and the fleur-de-lis are royal and national emblems. The crest was originally described as a bridge, but looked much more like a castle until 1974 (see image on postcard below), when it was shown as a proper bridge. The original Cambridge Castle stood on a hill just above the bridge. In 1974 were added and the crest was changed, otherwise the arms were not changed.
