The Basílica de San Isidoro is a Romanesque complex in León housing the Pantheon of the Kings, where eleven monarchs of the Kingdom of León are interred. The site features a 12th-century Romanesque fresco cycle in the royal pantheon vault, often referred to as the 'Sistine Chapel of Romanesque art.' Construction began in the 11th century over the remains of an older pre-Romanesque church dedicated to St. John the Baptist. The site functions as a collegiate church, museum, and an active place of worship. The onsite museum contains the Chalice of Doña Urraca, which some researchers have linked to historical debates regarding the Holy Grail. Architectural elements include a transition from Romanesque to Gothic styles, notably seen in the later 16th-century modifications.
