Created by the Architecture cell, the collection " Fenêtre sur " is dedicated to the disciplines associated with architecture. The second issue is devoted to Jean Glibert, with an essay of the Belgian architect and critic Raymond Balau, enriched by contributions of Marc Dubois, Cécile Vandernoot and Véronique Deleu. The work allows to place Jean Glibert's work in the second half of the XXth century, returning on its artistic anchorings and widening the field of its recent work to its whole career.
