A recent study has discovered a 2500-year-old ancient Greek city ten metres below the current street level in Naples, Italy.
Remains of the ancient city of Neapolis were discovered by installing detectors underground that were able to capture radiographic images.
The study, published in the Scientific Reports journal, observed known structures in the ancient city, as well as new structures such as a hidden, inaccessible burial chamber.
Researchers who participated in the study were aware of the Greek burials but were unable to access them until they used cosmic rays in a research technique known as “muography.”
According to Smithsonian Mag, Ancient Neapolis was a necropolis where Greeks built grand family tombs that grew into a town with paths and roads in “a city of the dead.”
A series of natural disasters led to the burial of the necropolis, which now sits below the bustling city of Naples in Italy.
