Park Güell is an urban park to the north of the Barcelona district of Gràcia designed by the great Antoni Gaudí, who planned and directed the construction of the park from 1900 to 1914 for Eusebi Güell as a luxury villa, where 60 houses for the richest families of the Barcelona bourgeoisie would be built. The sale of the houses was not as successful as expected and, a few years later, it became a public park. It is considered one of Gaudí's most colorful and playful works even though it was never fully completed.

The park extends beyond the structures covering the hill with stepped pedestrian paths and gardens amid the lush foliage. Near the base stands the house Gaudí had built for his own use in the park, the work of his disciple Francesc Berenguer (1905). The house has since been converted into the Casa-Museu Gaudí and houses furnishings designed by Gaudí as well as personal memorabilia. UNESCO declared Güell Park a World Heritage site in 1984.
