Project: The association Le Crneau has been in charge for 20 years to take care of the castle on the site of Les Prureaux. One of the aims of the association is to develop on the site environmentaly-friendly constructions. You will contibute to this project by building some removable wood accomodations and you will learn to use locally found and sustainable materials. Work: With the objective of making a sustainable accomodation, you will first discover the different wood ressources on the site. In order to show the value of this local ressource, you will build some removable wooden structures. You will also use some other sustainable and recycling materials to create these accomodations which will fit into the natural environment of the place. Leasure activities: you will have the opportunity to visit the area and some local towns (e.g. Moulins or Vichy), you will meet local handcraft workers and you will go hiking in the surroundings. Accomodation: in tents. Situation: Montcombroux-les-Mines, Chteau des Prureaux (Allier) 45 km from Vichy. Terminal: Saint Germain des Fosss
