The Autódromo do Estoril (officially, Autódromo Fernanda Pires da Silva) is a race course in Portugal, owned by state-run holding management company Parpública. Its length is 4.182 km (2.599 mi). It was the home of the Formula One Portuguese Grand Prix from 1984 to 1996.

Its first years saw many national races, as well as an occasional Formula 2 race. However, the course soon fell into disrepair due to the owning company having been taken over by the state between 1975-78, and a significant redevelopment effort was needed before international motorsport returned in 1984.

Estoril became a popular event on the F1 calendar, the setting for many well-known moments including three times world champion Ayrton Senna's first F1 win in 1985, Nigel Mansell's notorious black flag incident and subsequent collision with Senna in 1989, Jacques Villeneuve's overtaking Michael Schumacher around the outside of the final turn in 1996, and Riccardo Patrese's being launched airborne in a near-backward flip after colliding with Gerhard Berger on the main straight in 1992.

Estoril was dropped from the F1 calendar for the 1997 season, though it continued to play host to top-level single-seater, sports car and touring car events, including the FIA GT Championship, the DTM and the World Series by Renault.<ref>{{#if: The New Tracks

The circuit

The Estoril circuit was built in 1972 on a rocky plateau near the village of Alcabideche, 9 km from the city of Estoril, the beach resort lending its name to the circuit. The course has two hairpin turns, noticeable elevation changes, and a long start/finish straight.<ref>{{#if: The New Tracks

Throughout the years, Estoril has had numerous problems with safety, failing safety inspections on more than one occasion. After the death of Ayrton Senna at the 1994 San Marino Grand Prix, the track saw a chicane added which enlarged the circuit to 4.360 km (2.709 mi). Estoril sometimes has high crosswinds, which remind many of its Spanish counterpart, the Circuit de Catalunya which also has a similar layout. Many teams were fond of using Estoril for winter testing.
