Quarries of Paris - The network located in the Val de Grace hospital.

The old quarries of the Val de Grace are medieval. They were exploited from the 13th century to 16th century.

In 1621, Anne of Austria asked Louis XIII transfer Benedictine nuns of the Convent of Bievre in Paris. The venue was the current location of the Val de Grace.

In 1638, the architect Francois Mansart began construction of a church and an abbey. In digging the foundations, he discovers that he is above old underground quarries. These voids are surveyed, mapped and consolidated. But Mansart spending too much money and who is the architect Lemercier completed the job.

For the purposes of work, workers have built a staircase to the underground quarries and give the name of Mansart.
