Stories in Stone: A Geological Journey Through the Basilicas of Rome

As part of the Festival of Science di Rome, ISPRA is organizing, on April 18, the geological walk “Stories in Stone: A Geological Journey Through the Basilicas of Rome.”

Rebuilt after the devastating fire of 1823, the Basilica of Saint Paul Outside the Walls represents an important example of the restoration of early Christian architecture, while preserving its connection to its ancient origins. One of the building’s distinctive features is the extensive use of ornamental stones sourced from various areas of the Mediterranean.

The guided tour will offer participants the opportunity to closely observe these lithological varieties, appreciating not only their quality and aesthetic value, but also their historical significance—providing a unique chance to discover how architectural beauty intertwines with history and geology.
