Le Domus Romane di Palazzo Valentini
Foro Traiano 85, Rome, Italy, 00186
When the 16th-century Palazzo Valentini underwent a major renovation in 2005, the remains of two ancient Roman villas, thermal baths, and a public building—likely a temple—were discovered underneath the palace. Because the site was buried for centuries, the Domus Romane di Palazzo Valentini is remarkably well-preserved today. Marvel at original staircases, frescoes, mosaics, and inlaid marble floors with a multimedia tour.
The Basics
Because it was buried for newer palaces for centuries, the Domus Romane di Palazzo Valentini—or Roman Houses of Palazzo Valentini—archaeological site is well-preserved today, and visitors can still view original staircases, frescoes, mosaics, and inlaid marble pavement, which is protected by a glass floor. Multimedia light shows bring the ruins to life, revealing how these elegant villas—owned by Imperial Rome's most powerful families—once looked and offering visitors a glimpse into life in ancient Rome. In addition, a newly unearthed underground area opposite Trajan's Column holds the remains of a monumental public building; a virtual reconstruction of the column and its surrounding area show what they looked like during their heyday. These archaeological sites are only open to the public via a guided Roman Domus of Palazzo Valentini tour, so it’s essential to book ahead.
