One of the top attractions in London. My best advice is go early. We got there before it opened and the line was around 2 sides of the building. It went fast once it opened because it can hold so many people. We went straight to the crown jewels and had no line to get in. By the time we got out of the building with the jewels, there was an hour wait to see them. The line is in the sun so plan for that on a hot day. The entire fortress is neat, but the primary attraction is definitely the jewels.
