There are a number of interesting exhibits but the main attractions are the white tower, the crown jewels, and the fact that it's a castle in the middle of London. There are some decent views of the Thames and Tower Bridge. Be wary of long lines for the crown jewels, and it will likely be crowded. Be sure to go around the castle walls. There are a lots of exhibits along the route. Definitely a place you want to go if visiting London.
