History Emperor Louis the Pious donated in 815 Untermühlheim together with Obermühlheim (today called Seligenstadt), which were then in the Frankish Maingau to Einhard. The name Mühlheim goes back to the ten mills (Mühlen in German) which in earlier times stood on the banks of the brooks Rodau and Bieber. Today, though, only one mill has been preserved, the Brückenmühle. This can be visited each year on Whit Monday (German Mill Day). For a long time in the Middle Ages Mühlheim was Mother Church to the surrounding places of Bürgel, Offenbach, Bieber, Heusenstamm, Dietesheim and Lämmerspiel. The spiritual court for the affiliated communities belonging to the Mother Church sat in this time in Mühlheim. From the 14th century, the Lords of Hagenhausen-Eppstein exercised lordly rights (Hoheitsrechte) in Mühlheim. From the Middle Ages until 1819, Mühlheim and the once self-administering communities of Dietesheim and Lämmerspiel belonged to the Biebermark (a communally owned cadastral area), and the outlying woodlands belonged to the Wildbann Dreieich, a royal hunting forest. Within current town limits once lay a place called Meielsheim. In 1435, Mühlheim, as was so with many places in the area, was sold along with the Amt
