The Juan de Villanueva fountain is a monumental fountain that is a tribute to the 18th century architect Juan de Villanueva, author of many buildings and attractions of Madrid, such as the Prado Museum, the Botanical Garden and the reconstruction of Plaza Mayor. The fountain was built in 1952 according to the design of Víctor D'Ors, Joaquín Núñez Mer and Manuel Ambros and the sculptor Santiago Costa.
In 1995, the fountain was moved to its current location in the Parque del Oeste. She lost four groups of sculptures that had previously adorned her. One of them is now in the Dalieda de San Francisco Botanical Garden, the other adorns the Retiro Park. The fate of the others is unknown. However, the current location of the fountain is conducive to tourists. Water falling from a high bowl against a background of greenery and flowers, or a fountain illuminated at night is a popular photo theme.
