In 1900, the businessman Eusebio Guell commissioned Antonio Gaudi with a building consisting of 60 single-family homes for affluent families on the outskirts of Barcelona. Despite the project's modernity, it was a commercial failure that forced its promoters to close it in 1914. It is currently one of the most important public parks in Barcelona.

Gaudí experimented with architectural forms closely resembling the landscape and nature . The chosen site, with almost no vegetation, was stony and with significant ground irregularities. Gaudí took advantage of these characteristics by creating winding paths and using materials from the area, such as stones, to build covered spaces and porches supported with sloping columns.

Perhaps the most spectacular part of the park is a double set of steps with a central fountain in the shape of a dragon , all of which is covered in colourful "trencadís" mosaic (by the architect Josep Maria Jujol). The double set of steps leads to a large covered area that projects outwards like a large market, and is supported by 86 majestic Doric columns. The ceiling is adorned with colourful medallions. Above this area there is a large square, bordered by a long bench that defines an original meandering path.

The house that was built as a model of the dwellings of the future housing estate, and that was called Torre Rosa in reference to the Virgin of the Rosary, was inhabited by Antoni Gaudí himself from 1906 to 1925.
