What kind of stone was used for the construction of the Panthenon's dome in Rome?
marble
sandstone
granite

The porous light stone was used in the concrete of the dome to reduce its weight. Scientists estimated that, if normal weight concrete had been used throughout, the stresses in the arch would have been some 80% greater. The same technique was for the ceilings of the Colosseum.
