This is a beautiful building and i was surprised when i asked someone at the door if i could enter that they said I could but needed to go through a side door where i had to show my passport and then was allowed to walk around on my own inside. It’s a beautiful building with fantastic woodwork and amazing history. Being a big fan of financial markets it’s amazing to me that you can walk on the floor here, especially when they make it so difficult in the US. If you need to exchange currency, some of the best rates i saw were just across the street. It was also neat to see what i think were the specialists offices on the exterior of the exchange. What a great free site, to see and enjoy.
