Your tour of the basilica continues with the Tesoro, or Treasure, near the sacristy, where you can admire liturgical objects, historical memorabilia, and artwork. It's probably not as rich a treasure as you'd expect, but keep in mind that the German mercenary soldiers took it all in the famous invasion of Rome in 1527. I'd like to point out two sculpture masterpieces that were made over a thousand years apart: the Sarcophagus of Giunio Basso in marble from the 4th century AD with scenes of Christ's life, and the Tomb of Sixtus IV (the pope who had the Sistine Chapel built) in gilded bronze, by Antonio del Pollaiolo.
