In 1905, Gaudí travelled to Lillet to build the chalet of Catllaràs, a mountain refuge for the engineers of the coal mine that supplied the Asland cement plant in the nearby municipality of Castellar de n'Hug.

While in Lillet, Gaudí stayed in the house of the textile magnate, Joan Artigas i Alart, who had an estate named Font de la Magnèsia, on the Llobregat river.

[1] Gaudí had done a similar project, although on a smaller scale, at Park Güell which he was then building in the Gràcia District of Barcelona.

As he did with Parc Güell, Gaudí designed the Artigas Gardens fully integrated with the surrounding natural environment.

He also built an artificial grotto, a typical Gaudí hallmark, like the one he had designed for the cascade of the Parc de la Ciutadella.
