How did the culture of the germanic tribes differ from that of romans

The Germanic tribes were much more culturally set back than the romans in things like buildings, writing, and art. The Germanic tribes were mainly nomadic so they never settled down to build magnificent buildings such as the Colosseum. The Romans at one point switched over to christian religion and the Germanic tribes were pagan, so after the Roman Empire collapsed, Christianity almost died out in most of Europe.
