Archaeologists in France have unearthed the well-preserved corpse of a 17th-century noblewoman -- still dressed in her dress, bonnet and shoes. A unique set of circumstances preserved the corpse for more than 350 years. Anthropologist Rozenn Colleter described the woman as a "natural mummy."

A team from the French National Institute for Preventive Archaeological Research discovered the body in a hermetically sealed lead coffin during a rescue excavation on a construction site for a conference center in Rennes in northwestern France.

The coffin was first opened in March 2014. It was one of five -- among about 800 graves -- found at the site, which has housed the Convent of the Jacobins since the 12th century. Inscriptions allowed archaeologists to identify the nearly intact body.

The corpse was identified as Louise de Quengo, Lady of Brefeillac, who died in 1656. "We didn't know how well-preserved she was until we scanned her," Colleter says.

Restored bonnets belonging to de Quengo are on display. The corpse will be reburied once scientists finish all their testing.

Leg warmers, or chausses, were also discovered in the coffin.

After restoration, leather shoes with cork soles have regained some of their original appearance.

A lead reliquary in the shape of a heart was found nearby. It contained the heart of de Quengo's husband, who died in 1649.
