In the Second World War, the village suffered greatly under the bombings in 1944 and 1945. Fourteen people were killed in these raids, and more than a hundred buildings were utterly or partly destroyed, among them the kindergarten and the gymnasium. After the war, reconstruction was implemented through brisk building activity and a heavy inflow of inhabitants. Beginning then, Glattbach became a residential community with nearly 3,800 inhabitants, favoured by its proximity to the town and its scenically charming location. The inhabitants are mostly commuters who overwhelmingly have jobs in Aschaffenburg.
