On the left side of the nave over the entrance chapel near the transept. At the top of the monument (by Paolo Romano, c. 1470) two angels support the papal coat of arms: a black cross on which superimposed are five moons of gold. In the first box in relief is The Virgin with the Holy Child: on the one hand, Pius II still a cardinal and supported by S. Paul; on the other hand, S. Peter presenting the keys. Laterally, in special niches, are carved in high relief six virtues: Science with the torch, Fortitude with the column, Prudence with the serpent, Justice with the sword, Faith with the chalice, and Charity with children. The two Latin inscriptions tell of the record of Pius II and putting in place the monument in 1614. The pope is actually buried under the floor of the santuary
