One of my 2006 Europe trip includes one of the fabulous and expensive city in the world - London, England. It has rich history, royal family and afternoon tea. English is the language but it's totally different from America.
Buildings and streets has lots of color and character, and there's a lot of ancient castles. It is a city full of both modern tech and ancient history.
Also, there's one of the most famous family in the world - the royal family. Think about all the parties, jewelry, and history.
I happen to be able to go inside one of the castle by the London bridge, here's a funny story. See the below picture of the narrow stone stairway? I climb up to the castle but when I'm ready to go down from the same stairway, the guard told me not to go down the same way. They said it's only for going up and going down because it's too narrow. So I have to go to the other end of the room to find another stairway to go down. What a trip that is, but however, I do found more stuff to photography, so all the extra walking is worth it.
