Lorsch Abbey
In pre-Roman times, the Abtsteinach area was settled by Celts. In the Middle Ages, the area was held by the Lorsch Abbey. Expansion brought about by the second settlement drive led to the villages of Ober-Absteinach and Unter-Abtsteinach arising. In 1012, Abtsteinach had its first documentary mention as "possesa steinah". In 1232, the Lorsch Abbey was dissolved by Emperor Friedrich II, and ownership of its holdings passed to the Archbishopric of Mainz.
