A lavish thermal bath complex has been unearthed in Pompeii, the ancient city that was frozen in time following Mount Vesuvius’ eruption in 79 C.E. Archaeologists say it may be one of the largest discoveries of its kind.

Archaeologists in Pompeii have unearthed a “once-in-a-century” discovery which has been buried under piles of rock and ash in the ancient city for over 2,000 years. The news was revealed exclusively to BBC News.

The newly uncovered baths are decorated with sumptuous mosaics and equipped with a series of hot, warm and cold rooms in the manner of a spa.
