La Devesa Park in Girona, with an area of nearly 40 hectares, is the city of Girona's urban green space and one of the largest in Catalonia. It is demarcated by the Ter River to the north, the Güell River to the west, the Onyar River to the east and the Güell-Devesa neighbourhood to the south. Most of the park is populated by some 2,605 plane trees, but the centre of the park also has open, sunny spaces prepared for sports: the Devesa municipal sports area, a picnic area, urban gardens, and city cultural facilities like Girona Trade Fair and the Congress Centre Auditorium. Other uses made of the Park all year round are: the weekly street market, on Tuesdays and Thursdays, and, in late October, the Fair attractions of San Narciso, the city's patron saint. A large proportion of La Devesa Park's trees were planted in the 1850s, and some of them are as much as 55 metres high. The park has been declared an Asset of National Interest for it uniqueness. The park contains the French-style La Devesa Gardens, and a wide variety of both native and foreign plants.
