The Roman villa of Sant Amanç occupied a dominant place on the road leading inland. It was excavated upon the construction of the Eix Transversal motorway.
This important mosaic was found in the flooring of one of the rooms. Crafted of broken stones in different colours and from different sources, it is a work of outstanding quality that bears decorative motifs and animal and plant figures, befitting the tastes of this late stage in Romanisation.
