Museo Storico Artistico

Accessed from the left nave of St Peter's Basilica, the Museo Storico Artistico (Tesoro; Treasury) sparkles with sacred relics and priceless artefacts, including a tabernacle by Donatello and the 6th-century Crux Vaticana, a cross studded with jewels that was a gift of the ­emperor Justinian II.
