Secret Passage!
This was pretty cool. They open this "secret passage" only one a year, and we were able to walk through. It snakes behind the shops lining the streets, then across a roof, along ledges, and finally ends with a 10 meter walk between two huge buildings that are only about a foot apart from each other - I had to walk sideways and look up in order to pass through (this attraction wouldn't be too popular - or even possible - in the States given the size of the average American). This was one of the passage guards, making sure that we escaped (from what, I have no idea) safely.
