Formerly known as the Outlook Tower, the Camera Obscura and the World of Illusions sits on Castlehill, and is one of the city’s must-see tourist attractions. The camera itself is situated at the top of the tower, is over 150 years old, and affords a complete panoramic view of the city by focusing light down onto an inverted lens. The World of Illusions is a multi-floor, multi-technology experience full of weird and wonderful installations including the light Fantastic hologram exhibition and the Magic Gallery, in which seeing “is not believing”. Shrink yourself, see disappearing sweets and swap your heads around with your family and friends!
