Now that I've been to London, I want to go back all the more. We were able to see a lot of sites, but there were so many we only glanced at. One example is the National Gallery in Trafalgar Square. We walked to the Square, but did not have the opportunity to visit this famous art museum. There is simply so much to see and unless you have a few weeks, it is almost impossible to see everything you want.
We first saw the Notre Dame de Paris cathedral at night, and even then you could see it was something to marvel at. We didn't tour the inside until later, but it was just as grand on the inside. Photo by Tim Stanley Photography.
