Underground Rome: the Circus Maximus opens its secrets thanks to PNRR

Beneath the feet of those strolling between the Palatine and Aventine hills lies a world Rome has kept secret for centuries. Thanks to the PNRR Caput Mundi programme, that world is finally accessible: Rome’s most extraordinary archaeological sites are opening their doors with free guided tours, and the results are breathtaking.

The Circus Maximus you’ve never seen

The Circus Maximus is one of history’s greatest monuments — 600 metres long, capacity for up to 300,000 spectators, the beating heart of chariot racing in ancient Rome. But what visitors have seen until now was only the surface — literally.

Thanks to recent excavation and restoration work funded by the PNRR, the visitor circuit now expands with a new sector of the south-eastern hemicycle, previously unexplored. Archaeologists from Rome’s Sovrintendenza Capitolina have uncovered Trajanic-era structures, ancient paving, late-antique rooms linked to dwellings and craft workshops. Even traces of 18th-century buildings that rose above the Roman structures have emerged — ancient galleries repurposed as wine cellars.

The result is a journey through twenty centuries of history, made accessible through new walkways, staircases and multimedia displays.

Other open sites: a weekend among Rome’s hidden treasures

The Circus Maximus isn’t the only highlight. The Caput Mundi programme includes extraordinary openings across the city:

• Church of S. Urbano alla Caffarella — a Roman temple later transformed into a Christian place of worship, with 11th and 17th-century frescoes and a crypt Madonna dating to the 9th–10th century. Open Saturday 14 June, 10am–1pm.
• Roman Villa of Tor de’ Cenci — a suburban residence in use from the 1st century BC to the 5th century AD, offering a window into the private life of Roman aristocracy. Open Sunday 15 June, 10am–1pm.
• Mausoleum of Monte del Grano and Tomb of Largo Talamo — already opened to great success, with over 500 visitors on the first day.

All visits are free, led by Sovrintendenza Capitolina archaeologists, subject to availability.

Why now is the perfect time to visit Rome

Rome has always been the city where history is tangible. But these months mark something special: parts of its heritage that have never been accessible to the public are opening for the first time, returned to Romans and visitors alike through real investment in restoration and conservation.

If you’re planning a stay in Rome, this is the moment. From our Vatican City Deluxe apartments, right in the heart of the city, you can reach the Circus Maximus in under 20 minutes — and with a free weekend you’ll have time to explore everything the PNRR has brought back to light.
