Modern plastic chairs on the floor of the first church to be built in Rome, the Archbasilica of St. John Lateran (or as the neighbors called it, simply San Giovanni). It’s the cathedral of the bishop of Rome, and the Pope, putting it above St. Peters in the Catholic hierarchy. It’s known as Omnium urbis et orbis Ecclesiarum Mater et Caput: “Cathedral of Rome and of the World.”
