WHS with a name originating from a founding act
I have a bit more trouble with this one, especially when there is a lot of overlap with the other Connection or the already existing connection Legends and Folk Myths.
It is slightly tenuous and apocryphal but the belfry in Antwerp could qualify. A folk tale etymology of Antwerpen is that it is derived from the story of Silvius Brabo who killed a giant that was extracting tolls on the river Scheldt, which ena the town to be founded. In celebration of the giant slaying Brano cut off the giants hand and threw i,t which in old Dutch is "Hand Werpen". For those that have been there it explains that big fountain on the main square in front of the Town Hall which I had a feeling was part of the inscribed zone, though that could be wrong.
This is a myth, the name is derived from something else (wharf) (and also Antwerp isn't a name of a WHS)
