The VISIONS. Architectures publiques collection arose from the wish to promote public architecture in Wallonia and Brussels by developing the connections that architecture maintains with photography and writing. It offers up an approach to the different aspects of architectural language: the eye of a photographer, the perception of a writer, the testimony of the user, the critique of a specialist, the conversation with the designers, i.e. so many entry points that are open to anyone according to his or her individual experience or preference. Since 2002 the collection has been edited at the rate of one publication a year or once every two years.
