The Parthian Monument is one of the most important Roman-age reliefs from Asia Minor. In five thematic cycles it commemorates the Roman Emperor Lucius Verus, who established a camp in Ephesus during his Parthian Campaign of 161-165 AD. The individual pieces have been arranged in the form of a monumental altar, but this is only a guess at their correct arrangement, as they were not found in their original state. The friezes have a total length of about 70 metres, of which 40 metres are on display.
