Another Norfolk canal?

I debated with myself whether to pose this photo as a "where is this?" tease, but decided it really would be too unfair. Too much of a trick. It would have been fine for April 1st, but I've missed the opportunity.

This does look like a portion of derelict canal, doesn't it? And it is indeed in Norfolk, but is nothing to do with the North Walsham and Dilham Canal.


It's the moat of New Buckenham Castle which, judging by the exposed tree roots out of view beyond the bridge, is normally in water.

There's not much left of the castle, either. We didn't explore, but the circular keep is thought to be the earliest in England.
