The chapel of the Passing is a simple stone building which served as the infirmary for the first friary.

St. Francis passed the last days of his life here, and being placed naked on the bare earth, died here on the evening of 3^rd October 1226, after having composed the final verses of his Canticle of the Creatures:
"Praised be you my Lord, for our Sister Bodily Death from whom no living man can escape: woe to those who die in mortal sin; blessed are those whom she finds doing Your Most Holy Will, because the Second Death will do them no harm."

Every year on 3^rd October towards sunset, the National Commemoration of the Passing of the Patron Saint of Italy is solemnly celebrated.
