papal tiaras en

Papal crowns, now in the form of ornate beehive-shaped headgear, ornamented with precious stones and pearls. It is formed of three diadems, thus also called the "triregnum." The tiara is a non-liturgical ornament indicating rank, therefore it is only worn for non-liturgical ceremonies, such as the coronation of a pope, and in processions. Often seen in the coat of arms of a pope, with the crossed keys of St. Peter. Older forms were less elaborate.
