Early archeological finds prove a population in the region of Gladbeck already in about 2000 BC. It was first mentioned in 1020 as Gladbeki and was originally a small village of 300 inhabitants. The village with its five peasantries (Butendorf, Brauck, Rentfort, Ellinghorst and Zweckel, now quarters of Gladbeck) was arranged around St. Lamberti cathedral.
