When did de Gondi purchase the seigneury of Versailles ?
The earliest mention of the name of Versailles is found in a document which predates 1038 , the Charte de l'abbaye Saint - Père de Chartres ( Charter of the Saint - Père de Chartres Abbey ) , in which one of the signatories was a certain Hugo de Versailliis ( Hugues de Versailles ) , who was seigneur of Versailles .
