Underwater archaeologists have found a stunning marble floor among the ruins of a Roman city. The sunken city of Baie is located under the sea in the Gulf of Naples, Italy , not far from Pompei, and was once a luxury holiday retreat. Over the years, archaeologists have recovered various relics from the city and their latest impressive find is a multicolored marble floor, reports ILF Science .

The floor, which is being painstakingly recovered and restored, features thousands of slabs in different shapes and colours, put together to create beautiful geometric patterns. The discovery was shared on Facebook page, the Archaeological Park of the Phlegraean Fields. According to the post, the mosaic is made of marble as well as shell, mother-of-pearl and glass.

It would once have been the floor of a reception room in a villa owned by a high-status individual during the third century, it explains. The materials would have been second hand (for example previously used for other walls and floors), while the process of putting it together no doubt challenging and expensive, the post says. For centuries, Baiae was an affluent and fashionable seaside resort visited by Rome’s elite, including Julius Ceaser, Cicero and Hadrian.

The streets were lined with luxurious villas and people visited initially for the rejuvenating volcanic hot springs, said to have healing properties, and in later years for its hedonistic offerings. The latter led to the city picking up its relatively recent nicknam.
