Circuito de Jerez (Circuit of Jerez), formerly known as Circuito Permanente de Jerez, is a 4.428 km (2.751 mi) racing circuit located close to the city of Jerez de la Frontera, deep within the sherry-producing south of Spain. The project was led by the Spanish engineer Manuel Medina Lara, based on a preliminary idea from Alessandro Rocci.
