The views from the Argyle Battery are amazing, especially on such a clear day. The hill with the tall structure on the far right of the photo is Calton Hill, which I will have a post on shortly.
My favourite part was the dog cemetery. It's just such a sweet sentiment. You can see the little doggy headstones on the bottom left of the photo.
Watch out, England! Boom boom!
The Great Hall was not quite as great as I was expecting. I think Hogwarts has ruined castles for me forever.
This is the Fore Well, which is 34 metres deep, and supplied the castle with its water supply for centuries. That little blue-white circle is the sky reflected in the water below, which gives you some idea of just how deep this well is.
On turning the corner into this courtyard, a little English boy, aged around 7, spotted the Union Jack and shouted at the top of his voice "Yay! The England flag! We defeated the castle!" His mum was so embarrassed, and it was the funniest thing ever. I'm not going to lie, that might have been the highlight of my day!
