I went to the Tower again today. I was only going to spend half a day, but then I spent the whole day, because there's so much to see.
I didn't take a picture of where Overbury is buried because it's in the Chapel Royal, and the guide said not to take pictures. (And do YOU want to get in trouble with the people who guard the Tower? I don't.)
I also walked up the stairs to the top of the Monument, 300+ steps in a tight spiral. I have a feeling that restoration folks were quite fit!
