Augusta Treverorum: important Roman city, modern Trier.
The circus appears to date back to the earliest period of the history of Trier; the race track may have been created immediately after the city had been founded. However, the hippodrome, which was about 450 meter long, became truly monumental in the first half of the second century CE. It was renovated after 293, when the emperor Constantius Chlorus moved his residence to Trier.
There is nothing to be seen any more; there are many houses built over the ancient circus. Still, we know that the monument was connected to the aqueduct, and we may assume that there were fountains on the spina.
Not far from here was the amphitheater.
