The discovery came out of repair work at the Church of Saint-Philibert in Dijon, France, where the building itself had become part of the problem. Saint-Philibert had been used for salt storage in the 18th and 19th centuries. In the 1970s, workers installed a heated concrete slab over salt-contaminated ground, and the trapped, heated salts helped crack and damage the stone church. The notice set a March 26 bid deadline, listed an estimated June 1 start date, and described a 120-month duration. In the transept, archaeologists found a late medieval burial vault containing adults and children, according to France’s National Institute for Preventive Archaeological Research, or Inrap.
