Which corner combination is called the most famous part of Spa-Francorchamps?

The Raidillon de l’Eau Rouge combination is called the most famous part of Spa-Francorchamps.

The sequence comes shortly after the La Source hairpin. Cars descend toward the Eau Rouge stream, sweep through a left-right-left set of corners and climb steeply toward a blind crest at Raidillon. Its compression, gradient and limited visibility make it one of motorsport’s most recognizable challenges.

The names are often mixed up. Eau Rouge properly refers to the stream and the lower section of the complex, while Raidillon identifies the uphill section. In everyday racing conversation, however, the entire corner combination is commonly called Eau Rouge or Raidillon de l’Eau Rouge.

The complex has also been central to safety debates. A temporary chicane was installed at the entrance for the 1994 Formula One season after the deaths of Roland Ratzenberger and Ayrton Senna, but the original configuration returned in 1995. The corner was slightly modified for the 2002 Belgian Grand Prix.
