The unsuspected Haarlem Red Light District towards the end of this street at Begijnhof.
It is a small cluster of operation around Waalse Kerk Haarlem or Walloon Church Haarlem. Yes, a real church!
If you are curious, locate on the map this Protestant church building which dates back to 1262. You will not miss the decorated window brothels right next door. No photos allowed of course.
Should you need to know more, I would suggest ‘follow the crowd’. 🙂
