Camera Obscura & World of Illusions is situated at the top of Castlehill right beside Edinburgh Castle. Venture through five floors jam-packed with over 100 illusions. You'll need at least two hours to discover them all! A swirling light vortex; a maze of mirrors; a chance to swap noses with a friend; see yourself grow, shrink and stretch; play eye-spy with our city view cams; and mess with your mind with brilliant visual effects. Camera Obscura & World of Illusions is Edinburgh's oldest tourist attraction. Join your guide inside the mysterious 166-year-old Victorian rooftop chamber to see Edinburgh as you've never seen it before! Discover the Camera Obscura - a live, moving image of Edinburgh projected through a periscope, while hearing a fascinating and highly amusing tour of the city and Edinburgh's history. Surprisingly spectacular! Step outside onto our Rooftop Terrace and enjoy the best 360 degree views of Edinburgh, an unbeatable vantage point for the most breath-taking photographs. Open every day, all year until late!
