The "House of Elsewhere" occupies a former prison just behind the castle and is one of the most unexpected museums in Switzerland. Inside is a deep collection of science fiction, utopian writing, and what the French call "voyages extraordinaires" — Jules Verne first editions, pulp magazines, film props, original artwork from Métal Hurlant illustrators, board games, robots, and a permanent collection that includes material from the Space Odyssey film set.
Temporary exhibitions are often more interesting than the permanent display. They tend to focus on a single author, theme, or sub-genre — past shows have covered post-apocalyptic landscapes, the work of Philip K. Dick, and the visual language of comic book mecha. The museum also runs the adjoining Espace Jules Verne, a smaller annex with rotating exhibits, and produces academic research on speculative fiction.
