There can't be too many attractions in the world that offer visitors the opportunity to pick people up on their hands, squash them to a pulp and even make the traffic climb over paper bridges. Camera Obscura is one of them! Camera Obscura can be found inside a mysterious Victorian rooftop chamber close to the entrance of Edinburgh Castle. Inside you can see live moving images of Edinburgh projected onto a viewing table through a giant periscope. The device rotates 360 degrees and uses mirrors to project images of Edinburgh and the surrounding area onto a lense and then onto a large white disc. Try out the popular but disorientating Ames Room where you get the chance to become a giant and a dwarf in the same room! There's also a great view over the rooftops of the Old Town and beyond through the free telescopes.
