The Gardens of the Royal Palace of La Granja de San Ildefonso cover 146 hectares of landscaped grounds designed in the 18th century by Robert de Cotte. The site is world-renowned for its 26 monumental baroque fountains, many of which utilize an original gravity-fed hydraulic system dating back to the Bourbon dynasty. Unlike many contemporary gardens, these grounds preserve their original hydraulic engineering, including lead pipes installed in the 1700s. The layout follows a formal French style with geometric hedges and tree-lined avenues leading to expansive water features. Sculptural programs throughout the garden primarily depict classical mythology. The site functions under the administration of the Spanish National Heritage (Patrimonio Nacional). It remains one of the best-preserved examples of an 18th-century royal garden in Europe.
