El Capricho is a park in Madrid. The name capricho means "folly" in Spanish. It was created by María Josefa Pimentel, Duchess of Osuna on her estate at Alameda de Osuna, which was then outside the city of Madrid. It is landscaped in eighteenth-century style with formal and naturalistic features.
It is recognised as one of the most beautiful parks in the city.
The landscape design shows some English influence. Characteristically of continental gardens in the English style, there are a number of "eye-catchers" such as a hermit's house and a temple to Bacchus. Other features include a lake and a maze.
