Pierre de Crawhez was the first person to come up with the idea of closed circuit being used for racing. At the time all the major races were from city to city. The Circuit des Ardennes was 53.5-miles in length, in a triangular circuit. It ran along the highway from the town of Bastogne to Longlier, 16 miles to the east, then south to Habay-la-Neuve before joining the main road back to Bastogne.
Shortly before the First World War, the "Circuit" was transfered to Francorchamps.
