The club was a result of a merger of three previous clubs on 11 September 1945, namely DOSS (founded 6 November 1920), Constantius (27 February 1921 in the St. Johannes Bergmans patronaat) and Gezellen Vier (founded 9 April 1929 in de parochie van De Liefde, Da Costakade). Officially D.C.G. stands for Door Combinatie Groot. In 1968 the club achieved its biggest success when their Sunday amateur team won the national amateur championship of the Netherlands.
