The Roman mosaic with scenes from the world of Dionysos (c.AD 220/230) and the reconstructed funerary monument to the legionary Poblicius (c.AD 40) are probably the best-known exhibits in Cologne's Romano-Germanic Museum. Its collections are drawn from the archaeological heritage of the city and its environs, from prehistory to the early Middle Ages. Highlights are the largest collection of Roman glass in the world as well as outstanding collections of Roman and early medieval jewellery.
Numerous archaeological finds, relics of daily life in Roman Cologne, put the visitor right in the heart of COLONIA CLAUDIA ARA AGRIPPINENSIUM. Architectural elements, inscriptions, portraits, pottery, etc., illustrate the development of the ancient city.
The prehistoric artefacts on display are from the Stone, Bronze and Iron Ages: they were found in Cologne. the Rhineland and other selected European sites. Several archaeological monuments have been left in situ and are also open to the public.
The museum is also a research centre, with archives relating to the archaeology of the city, an extensive documentation on historical monuments and a specialist library (at present containing 30,000 volumes).
