Jean Dubuffet is a theoretician of Art brut and the most contested and known French artist of the post-war period. In 1969 he decided to build a place for his Cabinet Logologique and at his own expense. This assembly, called La Closerie Falbala, is a pure creation of the mind. This construction site will be considerable, it’s a real artistic and technical challenge. This monumental work is today one of the "youngest" historical monuments in France.
