Monsanto

Already scene of the Portuguese Sports Car Grand Prix twice during the 1950s, Monsanto Park also held a Formula 1 World Championship event in 1959. It was set in the hills north-west of central Lisbon and its variety of surfaces (including crossing a tramline at one point) made it a challenging proposition. The main straight was part of the road to Estoril with the remainder of the course made up of parkland roads. That was the last year that the full circuit was used.
