The Arched Bridge
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. The cement plant was owned by Eusebi Güell, a rich industrialist who was Gaudí's principal patron. 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. As thanks for the hospitality of Mr. Artigas, Gaudí designed these gardens for him.
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. He sent some of Park Güell's workers to Lillet, and the resulting stylistic and structural similarities between the two locations are obvious. 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
