Parc de Vallparadís, Urban park in Terrassa, Spain.

Parc de Vallparadís is a Y-shaped park in Terrassa, about 3.5 km long and averaging 100 m wide, formed by the Vallparadís and Monner torrents. It contains the Romanesque churches of Sant Pere, the 1110 Carthusian castle, the Textile Museum, the Casa Baumann, the Pont de Sant Pere and the Pont del Passeig, plus a 180 m swimming pool and a large-scale train.

The Vallparadís torrents were farmed until the late 19th century; the railway arrived in 1856 and Miquel Curet drew the first urban plan in 1878. The Pont del Passeig followed in 1895, and Manuel Ribas i Piera's special plan was built in three phases between 1991 and 1997. Excavations at Cal Guardiola in 1997 yielded some 26,000 Pleistocene fossils, about 3,000 of them mammals.

The name Vallparadís comes from the Latin Vallis Paradisi, recorded since 1346, when the first settlers arrived. The park hosts annual events such as the Jazz Picnic and the Festival of Colors, which draw thousands of spectators. The Carthusian castle of Vallparadís, dating from 1110, is now the main section of the Terrassa Museum.

The park has several entry points that connect well with public transit, making it easy to explore different sections. Visitors will find playgrounds, sports facilities, a swimming pool, and a miniature train service throughout the grounds.

The grounds contain a medieval castle and church complex that sit alongside modern gardens, showing how older structures have been preserved within the contemporary park design. These historic buildings are set somewhat apart from the main routes and offer visitors a contrasting experience.
