On the basis of Clunn's findings, Schlüter began a comprehensive excavation of the site in 1989, later directed by Susanne Wilbers-Rost. His finds are now displayed at the Varusschlacht (Varus Battle) Museum and Park Kalkriese, opened in 2002. In the following years, Clunn investigated the entire area around Kalkriese. The coins he discovered have made it possible to reconstruct the route taken by the Roman legionaries under Varus and to determine where they were ambushed and massacred. In Clunn's opinion, the march route corresponds exactly to the changing environment as described by Dio Cassius.
