After 50 years of neglect, Rome’s “lost” imperial palace Domus Tiberiana has reopened as an open-air museum. Until recently a crumbling and off-limits ruin near the famous Colosseum, the Domus Tiberiana palace — built in the first century AD and beloved by Nero — hopes to once again take its place as one of the city’s top tourist attractions. 

The ancient palace sits on Palatine Hill — the city’s oldest hill, overhanging Rome —from where imperial dynasties ruled for centuries. But over the years, the site fell into disrepair and in the 1970s, the Domus Tiberiana site was shut due to the structural instability of some of the ruins. The closure left behind what many Romans described as a “black hole” in the capital’s archaeological heart.
