Eau Lord... it's Spa's greatest (and most terrifying) corner
Eau Rouge was one of the first artificial corners in the history of motorsport (early road-type circuits were on closed public roads), when it was built in 1939 at Spa-Francorchamps to improve average speeds at what was already a phenomenally fast circuit.
When Eau becomes new
Originally, there was a sharp left at the bottom of the hill (you can still see the remains of it in the picture above, in front of the BP signs), which ran up to a hairpin and a very tight right at the old customs post on the German-Belgian border. When this was replaced by the left-right of Eau Rouge, immediately followed by the left of Raidillon, the result was one of the fastest, trickiest and most fascinating corners in the sport.
