Romano-Germanic Museum, Cologne.

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

“On the floor of the main room of the villa is the renowned Dionysus mosaic. Since the mosaic could not be moved easily, the architects Klaus Renner and Heinz Röcke designed the museum around the mosaic. The inner courtyards of the museum mimic the layout of the ancient villa.”
