Built in 1974 over the remains of a Roman villa, the Romano-Germanic Museum in Cologne houses an extensive collection of Roman artefacts from the Roman settlement of Colonia Claudia Ara Agrippinensium (named after Agrippina the Younger, born in Cologne), the capital of the Imperial Province of Germania Inferior. The museum houses the largest worldwide collection of Roman glasses including the Cologne cage cup and the miniature portrait of Emperor Augustus in turquoise glass. It is also home to the world famous Dionysus mosaic and the Sepulcher of Poblicius.
