In 1784, in his book "Variétés Bordelaises" , Father Baurein was the first author to mention the ruins of the town of Brion, whose Roman origin seemed probable to him.

In 1853, after visiting the place, Léo Drouyn gave a very detailed description of the site. Very impressed by the importance and variety of the Roman remains, he came to identify the town as Noviomagus quoted by Ptolemy in the second century A.D. .

In 1890, Camille Jullian, the famous historian of Gaul, confirmed the identification in his work "Inscriptions romaines de Bordeaux" and specified these ruins were the most important in the Medoc.

It was not until a more recent period that this archaeological research started again in a significant way :

First in 1966, in response to a request by Charles Galy-Aché and Jean Chevrier, Marc Gauthier and Pierre Anus identified of the remains of a Gallo-Roman theatre belonging to the Early Roman Empire period.

Next, in 1976, René Cathérineau's borings provided evidence of a pre-Roman dwelling.

In the end and above all, from 1985 to 1990, Pierre Garmy, director of the Historical Antiquities, assisted by Professors Louis Maurin and André Coffyn, students from the University of Bordeaux III and the local Archaeological Society presided by Claude Castagné, succeeded in setting up a training dig.

Thus, were excavated the remains of:

At the same time, the "Conseil Général de la Gironde" gave orders for an extensive resistivity survey to be undertaken; moreover, an effort was made to make the reception of visitors easier by means of descriptive notice boards and conducted visits in summer time.

For the moment, although many other remains are to be found, digging has stopped to wait for measures of protection or restoration in order to prevent the open structures from being damaged.
