The Nürburgring, simply known as "The Ring" by enthusiasts, is a motorsport race track in Nürburg, Germany. It was built in the 1920s around the village and medieval castle of Nürburg in the Eifel, which is about 70 kilometres (43 mi) south of Cologne, and 120 kilometres (75 mi) northwest of Frankfurt. Nicknamed The Green Hell by Jackie Stewart, it is widely considered the toughest, most dangerous and most demanding purpose-built race track in the world.
Originally, the track featured four track configurations: the 28.265 kilometres (17.563 miles) long Gesamtstrecke ("Whole Course"), which in turn consisted of the 22.810 km (14.173 mi) Nordschleife ("Northern Loop"), and the 7.747 km (4.814 mi) Südschleife ("Southern Loop"). There also was a 2.281 km (1.417 mi) warm-up loop called Zielschleife ("Finish Loop") or better known as Betonschleife, around the pit area. Between 1982 and 1983 the start-finish area was demolished to create a new GP-Strecke, and this is currently used for all major and international racing events. However, the Nordschleife is still in use.
