Workers renovating a Paris grocery store stumbled on hundreds of human skeletons buried underneath the building.
The burying ground was apparently part of a hospital cemetery that was used from the 12th century to 17th century. From CNN:
"What's surprising is the bodies were not thrown in (the graves) but were carefully placed there in an organized manner. The individuals, men, women, and children, were placed head-to-toe," to fit as many as possible in the grave, (lead archaeologist Isabelle) Abadie explained.
Abadie told BFM-TV that when the cemetery was shut down centuries ago, most of the remains were moved to the Catacombs of Paris.
"But apparently the job was not done well," she said.
