Jacques Simon is unmistakably a very important link in the renewal of French landscape architecture. For the first time in an oeuvre, Anglo-Saxon and Scandinavian garden culture are combined with typically Latin structures, with classic architectural landscapes. He works as often as possible in situ, and does not shy away from driving the excavator himself. Since the eighties, he has also been creating transitory landscapes: with heavy and less heavy equipment, he brings patterns in fields, cultivated fields, snow-clad grounds, and so on. The list of important realisations by this landscape architect is impressive, and so is his influence.
