The Porta Santa (Holy Door), the work of the Sienese sculptor Vico Consorti (1902-97), was installed in 1949. The door was donated as an ex-voto by Francesco Von Streng, the Bishop of Lugano and Basel in Switzerland, as an expression of gratitude to God that his country was saved from the horrors of war.
The Porta Santais only open during a Jubilee, or Holy Year, which normally takes place every twenty-five years. For the rest of the time the door remains closed and walled up on the inside.
Porta Santa Walled up on the Inside
The Holy Door represents Jesus, the Good Shepherd, and the sheep pen: "I am the door: by me if any man enter in, he shall be saved, and shall go in and out, and find pasture." (John 10:9, KJV).
The Sixteen Panels
The sixteen bronze panels are divided into groups of four by the coats of arms of popes who have celebrated Jubilee years.
All of the panels (bar one) depict scenes from the New Testament. The narrative begins in the top left corner with the angel expelling Adam and Eve from Paradise and ends in the bottom right corner with Pope Pius XII (r. 1939-58) opening the Holy Door on Christmas Eve 1949 to mark the beginning of the Jubilee of 1950.
