Rome officials announced the discovery of the largest Roman wall mosaic ever found, a monumental artwork measuring ten meters high and sixteen meters long. The mosaic, dubbed the “Great Mosaic,” was revealed on Tuesday beneath the Oppian Hill, the site of Emperor Nero’s famed golden house built between AD 64 and 68.

Historical context and description

Archaeologist Francesco Pacetti, who led the unveiling, said the mosaic dates to the first century AD. While it is unclear whether the piece was part of Nero’s private complex or a separate dwelling later incorporated into the emperor’s estate, the artwork offers a vivid bird’s‑eye view of a walled port city. The scene includes public squares, towers, a life‑size bearded philosopher with his muse, a young poet, and a theatrical stage framed by columns, garlands, and vegetal swirls. Blue and terracotta colors, now faded, depict the bustling harbor and its inhabitants.

Adjacent to the mosaic, a newly restored fresco called the “Painted City” was also uncovered. The ten‑square‑meter fresco, also from the first century, mirrors the mosaic’s cityscape, showing a port entrance gate, roads, a theater, and a temple.

Ongoing work and future plans

Excavation continues, with archaeologists working to expose additional sections that portray grape harvests and wine‑making. The entire site spans roughly 60,000 square meters of the ruins of Trajan’s Baths, which were converted into public baths in AD 109 and may have served as an ancient library.

Rome’s mayor, Roberto Gualtieri, said the city is installing walkways and lighting to allow visitors to appreciate the intricate details. He added, “We are giving this unique wonder back to the city.” The restored area is slated to host book launches and cultural events, honoring the site’s historical role as a place of learning.
