Hi Andrés, thank you for reaching out. I didn’t know that there was an official city tourist map of the inner city wall. For this particular part of the wall, it is quite simple: the Proefstraatpoort was located at the Calvariekapel on the Naamsestraat, while the Wolvenpoort was around Number 32 Schapenstraat. If you go there today, the southern walls of the Van Dalepark still marks the site of the city wall that used to link the two city gates. In the before/after photo above, you can clear see this wall (from the outside – extra muros).
