The Raspes du Tarn and the Dourdou valley

Embed this item to access it offline

The Raspes escarpments are a balcony of rocks overlooking the Tarn. They provide you with a series of uphill and downhill sections interspersed with majestic sceneries—an atypical route dedicated to experienced riders. 

From the outset, the ascent to the Causse of Saint-Affrique sets the tone for this long-enduring and exhilarating loop. Gradually, you enter deep inside the Raspes, this wild canyon surrounding the meanders of the river Tarn. Finally, after a substantial effort, the Dourdou valley, villages, and red sandstone colours hold a gentle and well-deserved finish for you!

  • History and heritage

    Village of Saint-Izaire

    The history of this village is intertwined with that of the old Episcopalian castle, which was formerly the Bishop of Vabres summer palace. The name of the village was first made mention of in an official document dating back to 862 AD.

    During the 12th century, continual invasions, acts of banditry and battles between feudal lords created a tremendous insecurity. This led to the building of battlements to improve the defensive system and providea safe haven to the neighbouring people during periods of turmoil. The castle and the fortified village date back to the time of the Vabres bishops who made the village their summer residence and a safe refuge.

    When the religious wars were over and peace restored, the protective wall lost its primary function and so today the façade of the castle has windows inserted along its length. The fortified gates were also demolished to allow the passage of carts or to expand the neighbouring houses. The villagestreet, footpath and house pattern has remained unchanged since the Middle Ages, and the beautiful 15th century facades and windowscan still be seen in some streets today. The old church part of the battlements had its vault lowered in 1635 to provide housing to the schoolmaster and guards. In 1650 repair works were started by the Consuls.

    Ardeliès 9 Carved Standing Stone

    This statue has undergone some changes, it displays breasts as feminine attributes together with a harness holding the”object” which are masculine features. Moreover, the ring of the “object” and one breast become confused. The belt chevron ornaments are meticulously crafted, and legs appear in relief on an evenly pitted surface. The back, shoulder blades and belt are depicted along with a central item. This could be an harness with a ring like those on the Ardeliès 1 statue, the Bancanel statue (Saint-Affrique) or the one of Saint-Jean-de-l'Hôpital (Montclar), all of these statues are not far away from one another.

  • Archeology

    Ardeliès 6 Carved Standing Stone

    This statue must have represented a masculine figure as the trace of a harness is noticeable on the left side on the back. Arms and buckled belt are also still visible. The features of the face and back were achieved by picketing the rock. This technique was frequently used on the statues of the Ardaliès either for the engraving of figurative elements (Ardeliès 6) or to smooth the surface on which embossed elements emerged in relief (Ardeliès 9).

    Ardeliès 1 Carved Standing Stone

    This statue displays several masculine features: the harness passing over the right shoulder and holding an “object” with a ring. The belt ornamented with a buckle, and the legs are clearly visible. The facial features are difficult to identify. On the back, the lines that extend arms or harness come to a stop on a central element with an unknown meaning. By analogy to the masculine objects, some suggest it may be a harness, but is it a warrior attribute, a body ornament or part of a garment? The issue remains unresolved.

  • Archeology

    Ardeliès 2 Carved Standing Stone

    This statue was subjected to several changes during prehistoric times as it displays both feminine and masculine attributes: one breast is visible and so is the masculine “object” which is a sort of dagger. This object is particularly detailed: ring and decorations with chevron ornaments that could represent the dagger sheath. The belt is represented by criss-crossed patterns and constitutes the only decoration of this kind, along with the grid pattern, which suggests the formation of the fingers of the hands. On the back, shoulder blades, belt and perhaps hair, represent the outline of a female figure.
