That was already one of my questions that came in my mind: is this legal, that I was led by wikipedia (non odbl-compatible license) to this building? But nobody could answer the question. So I developed this way, how Osmand helps me navigating to this buildings… because nobody told something against this; I hope that this is OK.

As I rememeber you understand German: question: http://forum.openstreetmap.org/viewtopic.php?pid=344118#p344118 and the answer is two posts further.

However I do not know the situation in Belgium. Maybe ask someone in the Erfgoed-Wikipedia project?

One additional thought: you know wikidata? The license is CC-0 there. I think that coordinates are included there also. So this is compatible…

Also very often the street and housenumber of the building is given (in the official heritage lists). This should be OK to usw to navigate to the building (although you see no Blauschwildje there). In Germany (Rhineland-Palatinate) I have never seen such a sign at monuments. Here in Northrhine-Westfalia some buildings have this.
