Héritages haut-médiévaux dans les édifices romans de Catalogne du Nord. Le cas de l’église abbatiale bénédictine à double chevet Sainte-Marie d’Arles-sur-Tech

The former Benedictine abbey of St Mary in Arles-sur-Tech (France, Roussillon), founded during the reign of Charlemagne, has conserved its Romanesque church, which was twice dedicated in 1046 and 1157. The edifice stands out in the architectural landscape of the Catalan and more largely Southern Romanesque Ages, by means of its imposing choir with three apses facing west, matching another one that, nearly the same, faces east. This organization raises a lot of questions of different nature, in particular about the link with the previous early Christian and Carolingian edifices.
