The oppidum is located on a steep hillside, at the crossroads of many important land and sea routes.
Down below, the Roman Via Domitia used to connect Rome with Spain. Today,
the oppidum dominates the plains of Béziers and its famous vineyards.
The view here is truly amazing, owing chiefly to the Etang de Montady, a drained wetland situated on the plain and just a few hundred metres from the oppidum. It is a real curiosity in itself, with fields that have radiated out from a central point like the rays of the sun since the ditches were first dug to drain the land in the 13th century. And the Oppidum d'Ensérune offers the very best view.
Running under the hillside, the Canal du Midi takes the 170 metre long Malpas Tunnel, bored in 1679
and the first tunnel in the world to have been dug specifically for a canal.
