The travertine quarries that built ancient Rome are carving rock for a new generation of temples

The same travertine quarries near Rome that built St. Peter’s Basilica and the Colosseum are still being dug out today, providing the distinctive pock-marked rock to build a new generation of churches, temples and mosques worldwide. It is prized by architects for several reasons: It’s strong, plentiful and can withstand any number of climactic and environmental assaults. Depending on how and where it’s cut, it has a variety of looks: rough or sleek, in various colors. One of the latest projects is a new travertine façade for the Church of Jesus Christ of Latter-day Saints temple in New York City.
