Chair of Saint Peter

The Chair is the cathedra of St. Peter's Basilica. Cathedra is Latin for "chair" or "throne", and denominates the chair or seat of a bishop, hence "cathedral" denominates the Bishop's church in an episcopal see. The Popes formerly used the Chair. It is distinct from the Papal Cathedra in St. John Lateran Archbasilica, also in Rome, which is the actual cathedral church of the Pope.

. The Chair has metal rings attached to each side, allowing use as a sedia gestatoria
