Vallparadís Park (in Catalan and officially Parc de Vallparadís) is a natural urban space located in the municipality of Terrassa, in the province of Barcelona, Spain. Its construction began in 1991, from several previous approaches during the 19th and 20th centuries, which culminated in the final drafting of the project by Manuel Ribas i Piera. The park was declared an Bien de Interés Cultural by the Government of Spain. From north to south it is about 3.5 km long, and averages about 100 m wide.
The first fossil findings in the area date back a million years; samples of Pleistocene flora and fauna have been discovered at the Cal Guardiola site, while the first evidence of human presence dates back to the Iberian period, found at the Egosa settlement. This site would eventually become Egara, now Terrassa.The park has a "Y" shape due to the Vallparadís torrent and the Monner torrent, which converge in the Monumental church complex of Sant Pere de Terrassa, a historical heritage made up of a patrimonial, archaeological and artistic ensemble, a fundamental piece of Romanesque art in Catalonia. It houses the Textile Museum and Documentation Centre, one of the main textile museum institutions, consisting of a library, an image bank and a fabric collection, and the Carthusian castle of Vallparadís, a fortification —also declared a historical heritage site—dating from 1110, the main section of the current Terrassa museum. In addition, the park has several architectural monuments of great importance such as the Casa Baumann, the Pont de Sant Pere or the Pont del Passeig.Inside the park there are different facilities —such as a 180 m long swimming pool or a large-scale train that runs through the center of the park— and events are held annually, such as the Jazz Picnic or the Festival of Colors, which attract thousands of spectators.
