From the Gallo-Roman period up to the end of the Middle Ages, the Alyscamps ("Champs-Élysées") was one of the most prestigious necropolises in the West. Its heyday came when the necropolis was Christianised, with relics from St Trophimus and the tomb of St Genesius. The transfer of the relics of St Trophimus to the cathedral in 1152 led to the demise of the necropolis. It was carved up by the lords, who offered their distinguished patrons sculpted sarcophagi, while monks took tombstones to build convents.
