The municipality of Kornwestheim consists of the town centre and Pattonville. The latter became a part of Kornwestheim only at the beginning of the 1990s, having belonged to the Gemarkung Aldingen initially. The settlement was established in 1954 by the US army. After their departure a Company bought the area from the Federal Republic of Germany and divided it between the towns of Kornwestheim and Remseck am Neckar. Pattonville has since been converted from a military to a civilian settlement.
