Camera Obscura & World of Illusions - The Royal Mile, Edinburgh, Scotland

Camera Obscura and the World of Illusions has been going for more than 150 years. It is partly a learning centre but also a funhouse and it spreads over five floors of the building. The rooftop terrace gives a 360-degree panoramic view of the city via the Camera Obscura. The other floors are filled with puzzles, optical illusions, a vortex tunnel and mirror mazes, giving visitors a mixtures of tricks of the mind and eyes and alternate realities.
