When the 16th-century Palazzo Valentini underwent a major renovation in 2005, the magnificent remains of two ancient Roman villas and thermal baths dating from the 4th century AD were discovered underground. After years of additional excavation, this 20,000-square-foot Domus Romane complex is now open to the public.
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.
