Race track corners were given names to make them recognisable and memorable. It is easier to recall the action at a uniquely named corner rather than its number.
In 2022 there will be 23 "turn 3's"

Eau Rouge is possibly the most famous and iconic corner in Formula 1. The series of turns through 3, 4, and 5 of the Circuit de Spa-Francorchamps make up Eau Rouge and Raidillon, just before the long Kemmel straight. Eau Rouge is named after a stream that passes through under the track, with water that is reddish due to the high amounts of iron it contains.
