What is the contact information for a Dutch monastary that offers
weekly intensive French lessons.

A similar question (monastery in Denmark):

Sharonlee,

The question linked above by fp may indeed be of interest to you,
particularly since Crea-Langues (the French immersion program in a
monastery described in my answer) was co-founded by Jan Deweerdt. I
believe this is a Dutch name. However, the monastery itself is not in
the Netherlands, but in the south of France.

Thanks for the information about the program in the south of France. 
While it is interesting, it is not the program I was looking for.

There are many similar programs to this in French and Belgium.  

The monastary program I heard about almost sounds like a kind of boot
camp for French.

I am still hoping someone will know about it.

In case you still get this and it is still relevant; you must mean
"the nuns in Vught". It used to be a convent, which it is not anymore,
but they still give language courses in, among other languages,
French. See http://www.reginacoeli.nl/ for more info. (Btw there is a
very pretentious institute in Spa, Belgium, offering heavy
competition: www.ceran.com)
