context_page_description: Seligenstadt is a town in the Offenbach district in the Regierungsbezirk of Darmstadt in Hesse, Germany. Seligenstadt is one of Germany's oldest towns and was already of great importance in Carolingian times.
context_section_description: Sometime about AD 100, during the reign of Roman Emperor Trajan, a cohort castrum was built on what is now Seligenstadt's marketplace and parts of its old town. Since the 16th century, this castrum has been referred to by the name Selgum. The 500 legionaries and auxiliary forces stationed there belonged to the Legio XXII Primigenia (or Roman 22nd Legion), based in Mogontiacum (Mainz). The cohort was known by the name Cohors I Civium Romanorum equitata and was responsible for security along the stretch of the Limes Germanicus running along the Main. With the fall of the Limes as a result of raids by the Alamanni in about AD 260, the castrum was abandoned, and the Romans withdrew farther behind the Rhine line. On the former castrum's rubble and on what is now the monastery area in a section of the Breitenbach valley arose the early mediaeval settlement of Mulinheim superior, or Obermühlheim.
