The flat we were borrowing (thanks, Shannon!) was just a few blocks from the Tower of London so we saw that first (and every day on our way to the Tube). You may or may not know that Boo is obsessed with all things Elizabethan right now and so we knew more about the Tower than we would have otherwise and we really enjoyed seeing it through her eyes and texting her photos. The British aren't as kitschy as we Americans are and thank goodness they haven't Disneyfied their historical sites, but they do make it fun, what with all the palace intrigue and the beheadings and the sex scandals and so on. I really wanted to see a castle on the trip and this was pretty close.
