The construction of a road network has been, along with the construction of cities, one of the main factors of Romanization. Roman geometers have often used Gallic routes. At that time, a dense network of tracks made it possible to reach all the surrounding urban centers and roads of first importance crossed the town. This is what enlightened Jean-Paul Eludut will come to tell during a small conference, illustrated with numerous maps and photographs, which will take place in Botquenven at 14 h. After this short presentation, the audience will be invited to a walk, commented by the speaker, on the Gallic highway Quimper-St-Malo which crosses the village.
