Буэн-Ретиро
In 1692 Giordano went to Spain at the invitation of Charles II. He stayed there for ten years, returning to Naples in 1702, following Charles' death. While in Spain, he painted major decorative schemes at the Buen Retiro Palace, El Escorial, the sacristry of Toledo Cathedral, The Royal Palace of Aranjuez. "The Allegory of the Golden Fleece", a ca.1697 fresco on the ceiling of the Casón del Buen Retiro is one of the possible reasons given for the building having survived when most of the other Buen Retiro palace complex buildings were demolished in the nineteenth century, now it's an annex of the Prado Museum Complex that holds a library for researchers. He also painted part of the frescoes at San Antonio de los Alemanes church and many pictures for the court, private patrons and churches. His pupils, Aniello Rossi and Matteo Pacelli, assisted him in Spain.
