Piazza di Pietra, Ancient Roman square in central Rome, Italy
Piazza di Pietra is a pedestrian square in central Rome featuring eleven preserved Corinthian columns that once belonged to an ancient temple and are now built into a building's facade. The space demonstrates how Roman builders' work became part of later structures without being removed or relocated.
The site originated as a temple built in the 2nd century AD to honor Emperor Hadrian, with construction commissioned by his successor. Over the following centuries, the area was built over many times, yet portions of the original temple's columns remained visible and were preserved within new structures.
The square serves as a daily gathering spot where locals and visitors pause to observe the standing columns, which remind everyone of Rome's layers of time. The way the ancient stones blend into modern urban life shows how the city lives with its past.
The square sits within walking distance of major attractions like the Pantheon and has good public transport connections nearby. Visitors should know that the space gets busier during midday hours, so arriving in early morning or late afternoon allows for better viewing of the columns.
At night, the ancient columns are sometimes illuminated with lights that display historical moments from different eras, bringing the site's story to life across centuries. These projections help visitors imagine what the original structure looked like hundreds of years ago.
