Around 1900, the Louvain photographer Edouard Morren made a unique photo report of the buildings comprising the University of Louvain. The 78 photographs were bound in a luxurious album, which is now preserved at the Louvain university archives. This new edition reproduces the numerous views of the most important sites of the university as well as photos of interiors that had never been documented before. A special focus is on the various laboratory facilities, that testify to the emerging scientific tradition of the university. The complete text is published in both English and Dutch.
