The other Roman ruins remaining in Avenches are this column where a temple once stood, a theater, which can be seen in the background (in the middle of the photo), a bath, and a gate.
Avenches (current population: 3,500) was known as Aventicum during Roman times. Aventicum was the capital of its province and had a population of around 20,000. The Roman amphitheater still stands in the middle of town. It continues to be used as a venue for concerts in the summer.
