A very famous museum  near the site of the workshop (5 minutes by foot) has been reserved exclusively for a private visit followed by a coktail party: no fee is asked to participant.

The museum is the "Institut du monde arabe".The Museum is dedicated to the Arabo-Islamic art and civilisation, from its origins to the present day. There are numerous art objects, Koran calligraphies, miniatures, collection of contemporary Arab art.
The Building has been built along the Seine in 1987 by Jean Nouvel and Architecture Studio. It is a very modern architecture which illustrates the Arab and Western civilisations.
After the visit, a coktail will be served at the top of the musem, with a very exitting view over Paris: in particular Notre-Dame and the Ile de la Cité
