サン・ジョバンニ・イン・ラテラノ大聖堂
The Clementine Chapel, also known as La Clementina, is a particular Roman Catholic chapel located within the underground necropolitan grottoes of Saint Peter's Basilica in Vatican City. It is the area where the relics of St. Peter were venerated in early medieval times, before his skull was removed to be housed at the Archbasilica of St. John Lateran.
