Turn 1: Turn 1 The first corner off the start-finish straight and a first-lap flashpoint, where Jenson Button collided with Sébastien Bourdais in 2008; the fast sweeping left that opens the lap is known as the Grande Courbe, though sources differ on whether it is Turn 1 or 2.
Turn 2: Turn 2 Part of the fast opening sequence leading toward the Estoril corner.
Turn 3: Estoril (Turn 3) A fast right-hander in a shallow dip, one of several corners deliberately modelled on and named after a turn at another circuit, in this case the Autódromo do Estoril.
Turn 4: Turn 4 A corner on the long uphill climb between the Estoril dip and the Adelaide hairpin.
Turn 5: Adelaide (Turn 5) A first-gear hairpin named after Adelaide's street circuit and the best overtaking spot on the lap; Jarno Trulli hit the back of Heikki Kovalainen here in 2007, and Alonso re-passed Kubica at the hairpin on lap 1 in 2008.
Turn 6: Turn 6 A tight hairpin known as the 180 Degrés just after Adelaide, prone to water pooling on the inside kerb in the wet.
Turn 7: Nürburgring Chicane (Turn 7) A chicane named after the Nürburgring; Lewis Hamilton took a drive-through penalty in the 2008 race for cutting it on lap 1 to gain an advantage.
Turn 8: Turn 8 Possibly the second apex of the Nürburgring chicane, though no source confirms the numbering.
Turn 9: Turn 9 A corner with no proper name documented in the accessible sources.
Turn 10: Turn 10 A corner with no proper name documented in the accessible sources.
Turn 11: Turn 11 The slightly uphill approach to the blind Imola chicane.
Turn 12: Imola Chicane (Turn 12) A high-speed chicane with prominent kerbs named after Imola, approached blind off the preceding uphill straight.
Turn 13: Château d'Eau (Turn 13) The circuit's highest point, named for an on-site water tower and reprofiled for 2003 from a regular corner into a right angle that opens into a curve.
Turn 14: Complexe du Lycée (Turn 14) The first element of the closing section rebuilt for 2003, a long left curve replacing the old Lycée chicane.
Turn 15: Complexe du Lycée (Turn 15) A right-angle 90-degree turn at the bottom of the descent, part of the 2003 rebuild.
Turn 16: Complexe du Lycée (Turn 16) The right-hand element of the closing chicane, reached via a short straight past the pit entry.
Turn 17: Complexe du Lycée (Turn 17) The left-hand element of the closing chicane onto the start-finish straight, rebuilt for 2003 to improve safety and overtaking.
