Edinburgh Castle and Camera Obscura

This morning I went out to see Edinburgh. The first thing I did was go to Edinburgh Castle. Edinburgh Castle is a huge castle that sits on a mountain. Technically it is not really a mountain, it’s just a hill of volcanic rock. I saw cannons, towers, and a big moat. After a while I started walking toward the Salisbury Crags. The Salisbury Crags are part of the bigger volcano Arthur’s Seat. The castle and the volcano are over a mile apart so I went into a gallery all about the camera obscura. A camera obscura is somewhere between a pinhole camera and a periscope. It makes it so lights or pictures can trick your eye. There were lots of things you could do, but my favorite was the Vortex Tunnel. The Vortex Tunnel was where you walked across a still bridge while a circular vortex spun around you. It felt like the bridge was spinning even though it never moved! After the gallery I went to a Scottish restaurant. I had Haggis, made from parts of a sheep, and chips, a food like fries.
