In the rich decoration of the so-called Sala Árabe (Arab Room), from the time of King Manuel I, the most outstanding feature is the panels of geometrical tiles that create a three-dimensional optical illusion, topped by friezes of relief tiles with heads of corn inserted in fleurs-de-lis. The Mudejar decoration of this space may reflect the powerful impression caused by the journey that King Manuel undertook with his first wife, Isabel, the daughter of the Catholic Kings, to the cities of Granada, Guadalupe, Toledo, Guadalajara and Saragossa, in 1498.
