The 2000-year-old shell grotto was used as an outdoor dining room and features a sizeable wall mosaic featuring brightly colored shells, coral and glass. Emanuele Antonio Minerva/MiC Rome, Italy CNN -- A five-year dig into the side of Rome's Palatine Hill yielded treasure last week when archaeologists discovered a deluxe banquet room dating from around the first or second century BC, featuring a sizable, intact and brightly colored wall mosaic. Estimated to be around 2,300 years old, the work is part of a larger aristocratic mansion, located near the Roman Forum, that has been under excavation since 2018. Almost five meters long (16.4 ft) and featuring depictions of vines, lotus leaves, tridents, trumpets, helmets and mythological marine creatures, the mosaic scene was painstakingly created using mother of pearl, shells, corals, shards of precious glass and flecks of marble. The piece is framed by polychrome crystals, spongy travertine, and exotic, ancient Egyptian blue tiles. What makes this discovery "unmatched," said archaeologist Alfonsina Russo, head of the Colosseum Archaeological Park in charge of the site, is not only the incredible conservation of the mosaic, but its decoration which also features celebratory scenes of naval and land battles likely funded -- and won -- by an extremely wealthy aristocratic patron who commemorated the victories on their walls. Being buried under the earth on Rome's Palatine Hill has protected this fragile mosaic from the elements for centuries. Being buried under the earth on Rome's Palatine Hill has protected this fragile mosaic from the elements for centuries. Emanuele Antonio Minerva/MiC The intricacy of the mosaic's depictions of victory have surprised the team working on the project. They show a coastal walled town with lookout towers and loggias -- which Russo said could be an ideal or a real-life location -- sitting atop a cliff designed with pieces of travertine rock. Scenes of sailing ships with raised sails also feature, alongside depictions of mythical sea monsters swallowing enemy fleets. Archaeologists are trying to ascertain whether the delicate -- and expensive, for the time -- coral branches used in the display came from the Mediterranean or the Red Sea (the nearest and most common oceans used by Romans to extract materials). A rare bluish glass paste also featured in the design likely came from the ancient Egyptian city of Alexandria, the team believe. 'Lost' ancient Roman palace reopens after 50 years of neglect "This banquet hall, which measures 25 square meters (270 square foot), is just one space within a 'domus' (the latin word for house) spread on several floors," Russo told CNN in an interview. "In ancient times, when powerful noble families inhabited the Palatine Hill, it was customary to use rich decorative elements as a symbol to show-off opulence and high social rank." The chamber, deemed a "jewel" by Russo, was an outdoor banquet hall overlooking a garden, likely used during summer to entertain guests. Such an elaborate space would also have been used to impress guests with water games, which were very popular amongst nobility at the time. "We have found lead pipes embedded within the decorated walls, built to carry water inside basins or to make fountains spout to create water games," said Russo. Work continues to uncover more of the secrets of the large home, which could have once belonged to a Roman senator. Work continues to uncover more of the secrets of the large home, which could have once belonged to a Roman senator. Emanuele Antonio Minerva/MiC Marco Rossi, professor of Roman antiquities and head of the mosaic lab at Rome's Universita degli Studi di Roma Tre pointed out that these summer banquet rooms were not only somewhere that hosts and guests would go to relax but also used by the mansion owner as a signifier of their wealth and rank. "Mosaics are usually found on floors, but this runs across the entire front wall and has been incredibly well-preserved," said Rossi of the piece. "It's not been ruined by the weight of debris -- as can happen to some mosaics on the ground -- and despite being delicate, it hasn't so much as chipped across the centuries." The discovery of an entire wall mosaic is extremely rare, Rossi added, not least because these pieces are more delicate than those for the floor which were designed to be walked upon and withstand pressure. 'Faces of Sanxingdui': Bronze Age relics shed light on mysterious ancient kingdom The location of the grand home has also helped the wall's preservation, scientists believe. Positioned on the side of Rome's famous Palatine Hill and subsequently covered over by centuries of mud and earth as the land has moved, the structure and treasures within it have been protected from the air and light by layers of ground. While this new discovery still has a lot of secrets to reveal -- why the property was abandoned and how long ago, for example -- Russo believes there is one mystery archaeologists could perhaps solve: The identity of its owner, likely a Roman senator. "The person was so rich they could afford to import such precious elements from across the empire to decorate this mansion," Russo said. "We have found nothing so far to shed light on their identity, but we believe more research might enable us to pinpoint the noble family." Russo and her team aim to open the space to the public in early January. "We (will) continue to dig the other layers and areas of this evocative place (to try to discover more)," she said. "It is really an incredible display of Roman luxury."
