In context of overlay "Things" – Tree – osm.org/node/1884421374 via StreetComplete 61.3:

How exact is mapping supposed to be? Because in reality this piazza has a very different tree layout than the one shown in the map which shows evenly distributed trees.
Actually there is an alley of trees (about 2 m wide) on the south side of the piazza, one large tree on each short side and no trees at all on middle or north side. On the other hand I.dp not want to delete any tree here because there are definitely more trees in reality than on the map- just elsewhere.

osmand routes bicycles here but this is a 1m wide raised wooden plank path with pedestrians on it. Bicycling is very inadvisable.here.

Warum sollte es eine Durchfahrtshöhe geben? Es ist ein normaler ebenerdiger Bahnübergang mit einer elektrifizierten Strecke.

There is no fountain. See photo.
