Sculptures and ruins displayed outside the entrance are merely the overture to a full symphony of Roman artefacts found along the Rhine. Highlights include the giant Poblicius tomb (AD 30–40), the magnificent 3rd-century Dionysus mosaic, and astonishingly well-preserved glass items. Insight into daily Roman life is gained from toys, tweezers, lamps and jewellery, the designs of which have changed surprisingly little since Roman times.
Plenty of remnants of the Roman city survive around the museum, including a street leading to the harbour and two wells. Other vestiges from the ancient settlement include a Roman arch from the former town wall outside the Dom and the nearby Römerturm.
