The Autódromo do Estoril (officially, Autódromo Fernanda Pires da Silva) is a motorsport race track 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.
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. Its original perimeter was 4.350 km (2.703 mi). 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, a chicane was added which increased the circuit length 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.
