Pope Francis is the first pontiff in centuries to be buried in the Papal Basilica of St. Mary Major. Most popes are laid to rest inside the Vatican Grottoes, a network of underground chambers and chapels located beneath St. Peter's Basilica, though it is not uncommon for them to request an alternative burial spot.
Francis chose the Papal Basilica of St. Mary Major because he often visited the ancient church to pray before and after his travels.
"I wish that my last earthly journey conclude precisely in this ancient Marian sanctuary where I went for prayer at the beginning and end of each Apostolic journey to confidently entrust my intentions to the Immaculate Mother and thank Her for her docile and maternal care," Francis said in his will.
It reflects his “humble, simple and essential’’ life, according to the archbishop who administers the basilica.
The last pope to be buried there was Clement IX, born Giulio Rospigliosi, who died in 1669.
