Road racing traditions in Europe, South America, Great Britain and the British Commonwealth nations grew around races held on paved, public roads such as the Circuit de la Sarthe circuit near the town of Le Mans, France, the Spa-Francorchamps Circuit in Belgium and the Mount Panorama Circuit in Australia. Certain European race circuits were situated in mountainous regions where the topography meant that the roads featured numerous curves and elevation changes, allowing the creation of sinuous and undulating race courses such as the Nurburgring in the Eifel mountains of Germany and the Circuit de Charade in the Chaîne des Puys in the Massif Central of France. These circuits presented such a challenge that they were both feared and respected by racers. The long Nurburgring with more than 300 metres (1,000 feet) of elevation change from its lowest to highest points, was nicknamed The Green Hell by Jackie Stewart, due to its challenging nature. The sinuous track layout of the Charade circuit caused some drivers like Jochen Rindt in the 1969 French Grand Prix to complain of motion sickness, and wore open face helmets just in case.
