Stockstadt am Main had its first documentary mention as early as the ninth century, if only through some townsmen who were obliged to pay taxes. These are listed as living in Stocestat, as the community was known then.
In the Middle Ages the surrounding forests belonged to the Dreieich Royal Hunting Forest (Wildbann Dreieich), which also had one of its 30 Wildhuben (farming estates whose owners were charged with guarding the king’s hunting rights) in Stockstadt.
The Zollhaus ("Customs House") on Hauptstraße long served the Elector-Archbishop of Mainz Albrecht von Brandenburg. It was built between 1514 and 1545.
The Leonharduskirche (Saint Leonard’s Church) is likewise found in the old centre of Stockstadt and dates back to the year 1773.
The St. Anna-Kapelle originally stood on the corner of Hauptstraße and Alter Stadtweg. It was torn down in January 1925 as a result of a decision by the community council. In 2007, the chapel was rebuilt on the historical model at another site to the west beyond Bundesstraße 469 towards Auhof, and dedicated on 6 April 2008.
