Ancient Roots and Modern Applications
The travertine quarries of Tivoli, Italy, have a rich history dating back to ancient Rome, where they provided the stone for iconic structures such as the Colosseum and St. Peter’s Basilica. This porous rock, known as lapis tiburtinus, is still being extracted today to construct a new generation of religious and civic buildings worldwide, including churches, mosques, banks, and museums. The unique geological formation of Roman travertine, primarily composed of calcium carbonate, is a result of ancient volcanic activity and mineral deposits, making it both durable and aesthetically versatile.
Architectural Significance
Fabrizio Mariotti, head of the Mariotti Carlo SpA stonecutting firm, emphasizes the global recognition of travertine, stating, “Travertine is a classic stone known all over the world. It’s a bit like carrying the light of Rome everywhere.” The firm has been instrumental in supplying travertine for significant architectural projects, including the Getty Center in Los Angeles and the Bank of China headquarters in Beijing. Currently, they are providing travertine for a temple being rebuilt by The Church of Jesus Christ of Latter-day Saints on Manhattan’s Upper West Side, showcasing the stone's continued relevance in contemporary architecture.
The Quarries: A Living History
The Tivoli quarries, characterized by their sulfuric springs and the sounds of heavy machinery, continue to operate as they have for centuries. The Degemar quarries, for instance, reach depths of 30 meters below sea level and are known for their bright blue sulfur ponds. Vincenzo De Gennaro, the current head of the Degemar quarries, highlights the historical significance of travertine, noting its use by Gian Lorenzo Bernini for the colonnade at St. Peter’s Square. De Gennaro asserts, “There is the concrete experience of a civilization dating back thousands of years that stands in the light of day and has been shining undisturbed for 2,000 years.”
The Appeal of Travertine
Marco Ferrero, a civil engineering professor at Rome’s La Sapienza University, points to travertine's connection to ancient Rome as a key factor in its appeal. He describes it as embodying the spirit of Rome: “Travertine is solid, resistant and noble but not showy like its cousin, marble.” This comparison underscores travertine's authenticity and its role in traditional Roman architecture, akin to the simplicity of Roman cuisine.
Criticism and Opposition
While travertine's durability and aesthetic qualities are widely praised, some critics may argue about the environmental impact of quarrying practices. The extraction process can disrupt local ecosystems and landscapes, raising concerns among environmentalists about sustainable practices in the stone industry.
