Venture through five floors jam-packed with over 100 illusions. 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 viewcams; and mess with your mind with brilliant visual effects. Join your guide inside the mysterious 166-year-old Victorian 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. Step outside onto our Rooftop Terrace and enjoy the best 360 views of Edinburgh, an unbeatable vantage point for the most breath-taking photographs. Get even closer with our range of telescopes and binoculars, all free to use. Astonishing in all weathers, all day, all year! Open late every day (apart from Christmas Day).
