The famous four rooms situated on the second floor of the Pontifical Palace were chosen by Pope Julius II della Rovere as private residence. The project was executed by Raphael and his school between 1508 and 1524.
Room of Constantine: this room was used for receptions and official ceremonies and was dedicated to Constantine, the first emperor to officially recognize the Christian faith. In fact on the walls we can see episodes of his life with battles and triumph of the Christian religion.
Room of Heliodorus: assigned to private audiences of the Pope and decorated with moments of the Old Testament, they are all pontiff’s political programme metaphor.
Room of Signature: originally was used by Julius II as library and office and takes its name from the court of the Holy See, but it’s also an iconographic programme to represent the three categories of the human spirit (Truth, Good and Beauty). There is the most famous fresco by Raphael the “School of Athens”.
Room of the fire in the Borgo: during the pontificate of Leo X was used as a dining room and showed his political aspirations thanks to stories taken from the lives of two previous Popes with the same name.
