Quid.fr is France’s Encyclopedia Britannica – and has this to say about the canton of Durban Corbières:
Vestiges Préhistoriques : 1 – Oppidum de Carla. 2 – Habitation Gallo-Romain au Roc de Carla
. . . and that is the sum-total of information that I can find on the site. I came across this meagre thread while researching the dolmen de Palats which lies 2 km. north. We drove past le Roc a few days ago :-
– and the only words for it are impregnable and inhospitable. With uninhabitable running a close third. The first two are desirable in a defensive stronghold – but its location is not obvious. As far as I am aware this oppidum is a lone outpost, far from the linked chain of defensive hill-settlements that runs east-west along the Aude river valley to command the long-established trade-route [that became the Via Aquitania and now the Autoroute des Deux Mers]. It has intermittent streams at the base of the rock [Carla is a version of Cayla, or Caylar – occitan for caillou, or pebble – a diminuitively affectionate term for these jagged outcrops that were favoured sites throughout the region]. But the main river that runs through this fairly barren part of the Corbières is La Berre, and that passes well to the south, through Durban – with its mediaeval castle high on a rock.
It is also possible that this was one of the more northern oppida belonging to the ibero-celtic tribes who built the oppidum de Ruscino [at Perpignan] later to become the ‘capitol’ of the Roussillon region.
Had I been alone I would probably have spent a painfully futile afternoon up there, hoping for a photograph of a crumbled wall or two – but I had wiser counsel beside me. So we drove on to the dolmen. This now joins the lengthening list of sites that require some local knowledge – and a set of crampons.
Co-ordinates for the oppidum will be available from S.E.S.A. at Carcassonne – or from me.
