More than 200 bodies have been found in communal graves under a Paris supermarket.
The bodies, dating back centuries, were laid out in a neat row, reports the Telegraph.
They were buried under a Monoprix supermarket, a popular chain store in France.
The site where the modern-day supermarket is situated was formerly a hospital.
The remains are thought to date from anywhere from the 14th century to the 16th.
However, it was previously thought that all the bodies had been removed by the eighteenth century.
Archaeologists said they were shocked by the discovery of a communal grave.
They now plan to carry out DNA tests to see if the people died of the plague.
Eight multiple graves have so far been found at the site, reports the Telegraph.
Researchers say each body was laid out with care.
Carbon dating is to be carried out also to see when exactly the bodies were buried.
