The Casita del Príncipe (Spanish for 'Cottage of the Prince') is an eighteenth-century house near the Royal Palace of El Pardo which is set in a hunting estate north of Madrid. The building was designed by the neoclassical architect Juan de Villanueva for the use of the heir to the Spanish throne Charles, Prince of Asturias. Construction began in 1784. The building is administered by the Patrimonio Nacional. Following restoration work in the early twenty-first century, the building is open to the public by prior arrangement. The artwork inside includes a fresco by Francisco Bayeu y Subías.
