The City has a fantastic profusion of churches. All are beautiful and they are usually open to look around.
There are dragons.. everywhere. It has its own flag, constitution and tradition. The British state treads lightly here. Even the Queen follows the rules.
The city is also known for peculiar cast iron bollards (with dragons added for effect).
You may think of it as the Vatican but devoted to Mammon and not God. Everyone is polite here but they tell the truth too.
The City is the strangest of all things- a non political government with a system that promotes on merit and not popularity. It concerns itself with economic issues and leaves the individual alone- the wet dream of the libertarian- and it actually exists.
