Rome has unveiled an extraordinary Roman-era mosaic, the largest of its kind ever unearthed. Located beneath the Baths of Trajan, this monumental artwork includes the "Painted City" fresco and "Muse and the Philosopher" mosaic. Public access started with viewings on September 12 and 13, followed by additional dates beginning October 2, now available Fridays through Sundays for groups of 15. Mayor Roberto Gualtieri announced this development via Instagram. Archaeologist Francesco Pacetti highlighted its historical significance, noting its origins in the first century and its depiction of a fortified port city. An accompanying museum has also opened, funded by a €500 million EU initiative.
