You refer to a post mentionning that the Belgian Council of State explicitly states that there is no passage thus not part of the public domain and then claim 'No indication that way/889476807 is really private.' its a bit off no... I mean the picture is clear there is no way through and Council of  States says there is no path... and never was.  Plus you can tell from the concrete pillar a sign was ripped off. 

There are two rows of barbed wire (three if you count the one on the walloon side) and a ditch that is 1m deep....
