Which of these is a London landmark?

Good question and answer but there is so much more to know than would fit in here.

I did hint

Do you have to pay to visit?

I visited the Tower with my daughter, I knew that ravens are the biggest corvids, but not that big. They're huge, having said that, a lammergeier vulture did a tour of the UK before heading back to the Urals. I watched a video of it being mobbed by ravens, they looked titchy compared to the vulture 🤣😂

Minaret of London - the setter is clairvoyant!
