Good call, Mike
it's indeed Le Golf National, site of the French Open since 1991.
From the French Golf Federation :
"Historical record
The French Golf Federation’s Executive Committee and its President Claude Cartier decided the construction of the Golf National in September 1985. Three years of work, from July 1987 to October 1990 finalised the course. It was then inaugurated by Ray Floyd, Greg Norman, Jeff Sluman and Marc Farry.
Hubert Chesneau golf-course designer was invited to create from past corn fields of over 139 hectares (350 acres), around the Chateau of Versailles (once home of Louis X1V), a Stadium course of International stature. On completion The Golf National would not only be the home for the French Open but also a centre for both National and International Championships. It would also be open throughout the year to the amateur golfer on a pay as you play basis.
The concept was based on opening a tip for roads or building diggings.
400 lorries a day moved a total of 1600,000 cubic metres of material with a further 600,000 removed to create water hazards. It was a tremendous challenge, which could have not succeeded without the total support of all involved.
One might be surprised with a links course with water hazards. These hazards and rolling terrain similar to that found in many Scottish Links courses became the concept. Trees took too long to grow in a short period of time when the course had to be, from 1991, a championship course. The hillocks or hummocks offered excellent facilities for television coverage of future championships.
As the course was created from a "clay base" it was essential that irrigation be of major importance so that the fairways would remain dry whilst any water would flow into the "hazards".
After the inauguration of The Golf National, the Albatros Course was the venue for the first French Open in June 1991 when, in a day of both wind and rain, Nick Faldo described the course as both tough but fair. Faldo was not the only world-class player to speak favourably of The Golf National, and it was of prime importance that many others supported Faldo. In March 1994 Golf Weekly ranked The Albatros Course 3rd European Championship Course through a survey carried out within the PGA Tour Professionals.
The Albatros Course is now the permanent venue of the French Open.
The Oiselet (Birdie) 9 hole course was opened in April 1991 and the Aigle (Eagle) 18 hole - in November 1991."
I will post tomorrow old GCA threads on Le Golf National.
