The Parco del Valentino, commonly known as Valentino Park, is a popular public park situated in Turin, Italy. Alongside the west bank of the Po River, the park covers an area of about 500,000 square meters, making it Turin's second-largest park. It was opened in 1856 and includes the remarkable Valentino Castle, an example of 16th-century Piedmontese architecture, which has been a UNESCO World Heritage site since 1997. The castle is home to the architecture faculty of the Politecnico di Torino. The park features a botanical garden and is a cherished green oasis in the city, providing walking paths, fountains, and areas ideal for picnics and relaxation. It is also renowned for hosting international events like the Turin International Book Fair and the 'Parco Valentino' car show. Visitors can discover medieval-style structures which are part of the 'Borgo Medievale' - a full-scale reconstruction of medieval village pavilions and shops. The park's combination of historic architecture, educational facilities, and natural beauty make it an integral part of Turin's cultural and social life.
