Secret tour through Murten

At the Museum Murten you receive a badge that unlocks six hidden rooms around the town. Each room contains its own mission as well as a light spectacle, including a room of infinity with reflections, an old prison cell in Murten Castle to be explored with torches, and a room where an electric circuit is closed through hand contact in order to make a heart pump. In the sixth room, prisms have to be moved to create crystallising light. The stations are spread across the town of Murten and are found with the help of maps.
