“The nine glass columns” more than 2m high, are located at the Rossignol rest area on the A6 motorway (located at kilometer 296, in the Auxerre-Beaune direction). They were designed for the Société des Autoroutes Paris-Rhin-Rhône and produced by Bernard Dejonghe, a glass sculptor who sees glass “as a means of expression in its own right, just like writing or painting. Bernard Dejonghe's encounter with glass dates back to 1984. He then met the American glass artist Howard Ben Tré, one of the first to use metallurgical mold fusion techniques for glass. Immediately immersed in intense technical research, he turned to mastering complex technologies, the only ones capable of restoring the emotion of the natural mineral world.
