So far the following have been established by readers.
*It is a castle.
*I have revealed the water in the shot is river and not a moat.
*I have given a clue: Think of Robin Hood.

*Two more clues:
>Think of a five line witty poem in the pattern of AABBA.
>Think not of a location in Robin Hood but a character.

Come on people! You have a clue as to which city this landmark is in and the person who built it. Jed's landmarks are no easier than this one!
