How about using the church as a landmark to navigate to the back street while cycling through the park — a totally valid use case. (Admittedly I usually exit the park here either on the right through the gate or on the left by the pavilion.)

Jeroen, buildings, even burnt down, are important features for navigation. Being able to see them is more important than knowing where a piece of land owned by an educational institution has its border.

TrickyFoxy: it did briefly show up *because* I changed the tags.

I disagree. Tags are not untouchable. If changing them to more widely supported ones ensures better accessibility, that should be done.

Jeroen, that’s not what the page says. It explicitly mentions that both are correct but only one is rendered. Which is exactly the case here.
