Visible from a distance, it indicated the presence of the city and of the Imperial temple located at the foot of the hill around the spring. It was the highest and most prestigious tower of the Roman town.
Octagonal in form, it was then composed of 3 levels on top of a pedestal. Today, the top storey has disappeared and it rises to a height of about 32m. From the top, the view over Nîmes is remarkable.
You can see Mount Ventoux, the Alpilles, the Vistre floodplain and the garrigue. A panel shows Nîmes in the Roman period.
