Located in the historic Plaza del Rey on the western edge of Chueca, this remarkable little Habsburg building was the late-16th-century creation of El Escorial architect Juan de Herrera. Celebrated visitors over the years have included Charles I of England and the Marquis of Esquilache, who caused a minor mutiny when he tried to abolish the wearing of capes and broad-brimmed hats in the 18th century.
