One of the best-preserved ancient Roman homes on the Palatine Hill is opening to the public for the first time. But it's happening via a livestreamed tour of its hard-to-reach underground frescoes and mosaics. The House of the Griffins was first discovered during the excavations in the early 20th century of the Palatine Hill. The hill is located just off the Colosseum. It was known for temples and homes of leading citizens during Rome’s Republican era. It became the aristocratic quarter during the Roman Empire that followed when new palaces were built on top of the older homes. The livestreamed tours will be held weekly starting on March 3.
