The Basilica … is permitted to display the crossed keys, which indicate its connection with the Holy See, on all its printed materials and insignia. This outward sign and privilege conferred upon a Basilica is a prominent feature of the Papal Seal. The “keys” symbolize the keys to the kingdom which were symbolically entrusted to Saint Peter by the Lord himself. The crossed keys may also be displayed on the facade (exterior) of the Basilica; they may be used in banners and in the seal of the Basilica itself. A special Parasol—the ombrellino—in the Papal colors of yellow and red is displayed half-open in or near the sanctuary and may be carried in procession on special occasions. A special bell mounted on a pole—the** tintinabulum**— is also kept in the sanctuary and could be carried in on solemn occasions. These two items are special, visible symbols which link the Basilica with the Holy Father. These items indicate the church’s readiness to announce and to welcome the Pope should the occasion ever arise.
