Only two areas have been excavated :

The first area is an ancient settlement dating back to the eighth century B.C. at least.
Here, you can see remains of an Iron Age home (C1), with fire places , a bronze-smith's foundry and some postholes.
The Gallo-Roman buildings, which came next, appeared about the middle of the first century A.D. ; the most outstanding is a big one, identified as public building (C2).

Above the foundations the footings of the walls can be seen ; the walls sat on these footings made of carefully laid rows of bricks.

In the second area two long buildings can be seen, both made in the same manner and both facing the East.
Every house has four rooms opening onto a covered gallery supported by columns.

The parallel walls, all turned east, like the public building and the temple , give evidence of real town planning.
