Oke... Wat is your source?  A survey?
I think there is only one Hildebrandmonument.

I think there is only one fountain. 
The statue of Hildebrand himself is situated south of the fountain. Thats also on the map. 
They are mapped in a relation.
Hildebrand look from a distance to the fountain in the north.
Wher you put your fountain at the junction Oranjelaan is nothing. It;s a junction.

Because it's mapped in a wrong relation you don't see the statue on the map. 
You see the statue in the middle of the fountain. 
I may change the relation. 
The statue and the Bronnefountain are in fact one 'monument'
