The Roman-Germanic Museum (German: Römisch-Germanisches Museum) is an important archaeological museum in Cologne, Germany. It has a large collection of Roman artifacts from the Roman settlement Colonia Claudia Ara Agrippinensium, on which modern Cologne is built. The museum protects the original place of a Roman town villa, of which the large Dionysus Mosaic remains in its original place in the basement now, and the related Roman Road just outside. In this respect the museum is an archaeological site.
