The Celtic people of Rauraci lived in this area after 800 BC. They joined the great exodus of the Helvetii in 58 BC (defeated by Caesar that year at Bibracte, near Autun).
After the establishment of the Roman Colonia Augusta Raurica (Kaiseraugst), 44 B.C., the area was also inhabited by Romans. Between the 5th and 6th centuries, the Alemanni immigrated to this region. The first documented mention of “Metzerlon” dates back to 1194. The monastery of Mariastein was built from 1636 to 1655 and consecrated in 1655.
