Summary

A new Latter-day Saint temple in New York City is being constructed using Roman travertine, a distinctive stone sourced from quarries near Tivoli. The Mariotti Carlo SpA firm has been carving the material for several generations, fulfilling architectural commissions worldwide. Notably, they supplied travertine to the Getty Center and Bank of China headquarters. Fabrizio Mariotti, head of his family’s business, describes how Roman travertine reflects light uniquely, making it a classic stone known globally. This type of limestone, formed hundreds of thousands of years ago from mineral deposits in sulfuric springs around Tivoli, is prized for its durability and aesthetic appeal. The quarry site at Degemar, where Gian Lorenzo Bernini sourced the white travertine for St. Peter’s Basilica colonnade, still operates today. This temple renovation project by the Mormon Church reflects ongoing global usage of this ancient Roman stone in contemporary architectural projects.
