We arrive to room 7 crossing the door which was the palace external entrance until the fire that took place in 1372 in the bishop’s houses. After that fire, Lope Fernández de Luna, archbishop in Zaragoza, and King Pedro IV, “the Ceremonious”, rehabilitated the palace because they used it as a usual residence. They both promoted the new Gothic-Mudejar palace, bigger than previous one. Mudejar artists were employed to raise and decorate the new palace. They were Muslims people settled in Christian territories that preserved technical and stylistic elements inherited from their ancestors which were captured in pieces of art of Christian Maecenas.
