La Mandria Regional Park is a park in the Comune of Venaria Reale and Druento, near Turin, northern Italy. Founded in 1978 by the regional council of Piedmont, it occupies a wide area between the Stura di Lanzo torrent and the north-western part of Turin and Venaria.
It is the second largest enclosed park in Europe, with a surface of some 3,000 hectares, bounded by a 30 km long wall built in the mid-19th century by Victor Emmanuel II, who had moved to the castle here (the Borgo Castello) the residence of his morganatic wife, Rosa Vercellana. The park included one of the last relics of the large forest which once covered the whole Po Plain.
