An emergency excavation at 18, rue des Magnans, Aix-en-Provence, brought to light vestiges of a settlement dating from the 2^nd century AD, located in the vicinity of the forum. Two building structures partly excavated were found on either side of a passage on terraced ground. Among the most remarkable finds is a particularly well preserved polychrome mosaic, decorating the triclinium floor. In the triclinium we also discovered frescoes remaining on the lower part of the walls.
