A Parc-aux-Cerfs (literally, stag park), in France, was the name given to the clearings that provided hunting fields for the French prior to the French Revolution.
The Parc-aux-Cerfs was an area in the grounds of the Palace of Versailles used as the name for a mansion there, where young mistresses of Louis XV were accommodated, being taken from there to the palace to visit the king. The arrangement, it is often supposed, was supervised by his main mistress, Madame de Pompadour, who remained close to the king, but no longer did the physical work. However, Nancy Mitford states in her Madame de Pompadour (1968 revised edition) that "[she] had nothing whatever to do with it".
