Rebuilt after the Second World War, the courses have been modified and reduced to the Vineuil ''Old Course'' course completed by the 9-hole Longères course. The Canal route has been abandoned. The layout of some holes is still noticeable when arriving at the golf course and around the canal de la nonette.

Mr. Jean-Louis Dupont wanted to restore two 18-hole courses in Chantilly by creating, with the architect Donald Steel, 13 new holes. The Vineuil ''Old Course'' course has been modified by 3 new holes and an extension of 10 holes has transformed the Longères course into an 18-hole course with international standards.
