Marcodurum
Marcodurum in North Gallia. Some of the cohorts of the Ubii were cut to pieces by the troops of Civilis at Marcodurum, which as Tacitus observes (Hist. 4.28) is a long way from the bank of the Rhine. The termination durum indicates a place on a river; and Marcodurum seems to be Düren on the Roer. The Frank kings are said to have had a palace there, named Duria Villa or Dura.
