Around 16 BCE the Romans founded Augusta Treverorum on the Moselle, the origin of Trier, often considered Germany's oldest city. It later became an imperial residence and capital of the Western Roman Empire under the Tetrarchy. The Porta Nigra and imperial baths survive as UNESCO World Heritage monuments.

## Why it matters
Trier became one of the great cities of the late Roman world on German soil.
