What material is the dome of Rome Pantheon made from?

concrete
marble
sandstone
wood
The temple - 43 meter in diameter - was built by emperor Hadrian. Its dome with 8-meter wide oculus was built of un­re­in­forced concrete that has been a mystery for ages. The weight of Roman concrete used to build the mono­litic struc­ture is merely 1/5 of common con­crete. Such effect was achieved by mixing in of volcanic tuff and pumice.
