Will new technologies offer a viable alternative to temporary exhibitions? That's the question that we'll try to answer through the Bruegel box, an immersive art project by the Royal Museums of Fine Arts of Belgium. This project is the concretization of a deep reflection on the changes taking place in the field of museology. In this digital age, the Bruegel box (or any other painter's box) will enable us to explore new possibilities and will become the setting for a new museum space. The technology will serve the art, facilitating its access when physical transportation becomes increasingly binding. It also allows us to expand the museum experience and the meeting with the art pieces, by exporting the project abroad when the work itself can't be loaned overseas anymore.After an introduction of the project, from the original ideas that initiated it to its actual production, we will share our experience with the delegates. We will review both the technical and human difficulties that were faced throughout its production. Our overall aim is to raise questions on the future of museums in the digital age, opening up a debate. Is it this the future of the temporary exhibition? Will technology offer an alternative to broadcast our collections and enable museums to stay economically sustainable? Will future generations still be more likely to visit museums if we only can display digital or 3D printed duplicated masterpieces in order to protect our cultural patrimony? How to find the good balance between entertainment and scientific researches? And what about the "aura" of the pieces of art (W. Benjamin)? By being the 21st century museums, we need to redefine our fundamental missions.
