Stockstadt am Main

The Romans built a castrum at Stockstadt, as part of the Limes Germanicus. In the 1st century AD a small earthen fortification was erected. Around the year 100 it was replaced by a full cohort fort further to the southeast. This castrum had a size of 3.2 ha. Over time, it was occupied by the cohorts III Aquitanorum, II Hispanorum and I Aquitanorum. Stockstadt was also the site of a "de:Benefiziarer station" (i.e. a road house).[3]^: 30

After the withdrawal of the Romans from the area, the regional population declined. Burgundians and Alemanni moved through the lower Main region, but it was only under the Franks (after 500 AD) that the population density again rose noticeably. Their settlements often did not simply grow out of the formerly Roman cores but included separate newly established sites.[3]^{: 30, 66–7}

At Stockstadt, a Frankish graveyard was discovered to the northwest of the Roman structures. The Frankish settlement was likely located nearby, on the right bank of the Gersprenz, north of the former Roman structures. The initial parish church and graveyard were located not in this area but around 700 meters to the southeast, at the location of the former castrum. It is likely that a separate settlement was still in existence then at this site and it may even have been more important than the other site. The parish church was dedicated to the saints Marcellinus and Peter, the patrons of Seligenstadt Abbey, to which Stockstadt temporarily belonged. It is unclear, whether this settlement was later abandoned or moved to the northwest. Later during the Middle Ages, the settlement between Gersprenz and Main was fortified by a wall with towers and moat. The church initially remained at the southeasterly location, however. At the site of the current church, the Leonhardskirche, remains of an earlier structure only date from the Gothic period.[3]^: 65–6

Stockstadt am Main had its first documentary mention as early as the 9th 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.

Eventually the community itself was named in writing for the first time in 1024. Stoddenstat was donated to Fulda Abbey by Henry II, Holy Roman Emperor. This lasted until 1309, when Stockstadt was given to the Archbishopric of Mainz.

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.

St. Anna-Kapelle

• The Zollhaus ("Customs House") on Hauptstraße long served the Elector-Archbishop of Mainz Albrecht von Brandenburg. It was built between 1514 and 1545. However, the site likely was the location of an older water castle.[3]^: 65
• The Leonharduskirche (Saint Leonard's Church) is likewise found in the old centre of Stockstadt and dates back to the year 1773. The foundation of the tower is older, built in Gothic style.[3]^: 66
• The St. Anna-Kapelle originally stood on the corner of Hauptstraße and Alter Stadtweg. It was demolished 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.
