The area was probably first settled by ancient humans in the 12th millennium BC. The Romans left some traces here in AD 85, when they built a limes frontier wall at the Neckar River. Tübingen dates from the 6th or 7th century, when the region was populated by the Alamanni people. Some historians argue that the Battle of Solicinium was fought at Spitzberg, a mountain in Tübingen, in AD 367, although there is no evidence for this.[citation needed]
