The image is a photograph of a brown sign with white text on it. The sign is located on a wooden post and is located in a wooded area. The text on the sign reads "Site du Pont du Gard" which translates to "Site of the Pont of the Gard" in English. Below the text, there is a map of the Roman aqueduct of Nimes, which is part of the Nimes River. The map shows the route of the river and the surrounding area. 

On the right side of the sign, there are two arrows pointing towards the river, one on the left side and one in the center. The arrows indicate the direction of the water flow, while the arrows point to the right. The river is shown in blue and the water is in a light blue color.

The sign also has a small illustration of a bridge on the top right corner. The bridge appears to be made of stone and is painted in a traditional Roman style. The background of the image is blurred, but it seems to be a natural setting with trees and greenery.
