Mr Monkey got off the Underground at Tower Hill, and walked to Tower Bridge. The wall on the right of the first picture is the outside wall of the Tower of London. Mr Monkey crossed the bridge, wondering why it was painted that colour. He didn't climb to the top of the bridge, but he would have done, if Mr Rik hadn't complained.
You can read about what Mr Monkey was prevented from seeing at the Tower Bridge Exhibition website.
