The restored ruins of two opulent Roman villas and private thermal baths will open to the public Saturday, along with a 3-D reconstruction that offers a virtual tour of the luxurious residences discovered in downtown Rome.

The 19,375-square-foot complex, dating from the second to fourth centuries, features well-preserved mosaic and marble floors, bathtubs and collapsed walls that archaeologists believe belonged to a domus — the richly decorated residences of Rome's wealthy and noble families.
