 After the Franks expanded into the area, five ancient Alemannic settlements were subsumed in a royal court location that is the basis of the present-day town.At the former settlement of Gendach, on the Schozach near Ilsfeld, there was a small motte and bailey castle, no traces of which remain.The royal center at Ilsfeld led to new settlements in the area, such as Westheim (Neckarwestheim), Ostheim (Auenstein) and Talheim, named for their relationship to Ilsfeld and marked as Frankish by the termination -"heim".
