Domus Romane di Palazzo Valentini

Palazzo Valentini, an active government building housing the offices of the Province of Rome, sits directly on the site of ancient noble residences that archaeologists began systematically excavating only in 2005, uncovering the remains of at least two large domus (Roman townhouses) complete with mosaic floors, hypocaust heating systems, and decorative marble that suggest genuinely wealthy, high-status occupants during the imperial period.

What sets the site apart from most Roman archaeological visits is how the discoveries are presented: rather than leaving visitors to interpret bare foundations and fragmentary walls, the site uses projected light, sound and digital reconstruction technology to rebuild the ancient rooms virtually in real time above the actual excavated remains — columns, ceilings, mosaic patterns and wall decoration appear projected onto the ruins themselves, dissolving and reforming as the guided narration moves through each room's history.
