Image would be useful to confirm it is not the same as nearby public bookcase which has image suggesting it can also be used as give box.
(has labels allowing shoes, tools, hardware, discs, something??, (plants/)seeds, books)

Some poems can serve as a memorial, but this one seems to be more of a poem which serves as (journey-based) artwork. I would suggest using instead
https://taginfo.openstreetmap.org/tags/artwork_type=poem
(note, wiki linked on this page is offline apr 26 and there have been some outages due to scrapers etc.)

Also, the name is either some word(s) of the poem (usually first line), maybe somewhere mentioned in the book they wrote about this route, or no name ( in which case noname=yes )

For your information; it is part of a route and you are welcome to look for the other plaques and create a route relation (or site type relation, if you prefer, though it is mostly not supported) which includes every plaque (without a role). This route can then have a 'url' for example
https://www.visitzuidlimburg.nl/te-doen-in-zuid-limburg/routes-in-zuid-limburg/detail/gedichtenroute/60121/
(since there seems to be no official 'website')

Hey BhavyaKhatri,

Welcome to OpenStreetMap.

If you would like to contribute to the OpenStreetMap project, there are a few ways to do so, see
osm.wiki/How_to_contribute

If you would like to contribute to the iD editor, or similar applications, please read up on the Readme, Code of Conduct and Contributing files when they are available. They can be found on the GitHub repository, for example here
https://github.com/openstreetmap/iD/blob/develop/README.md#participate
Feel free to make a PR on GitHub. Make sure to describe how you got to your solution and how you know it resolves the issue properly.
You can always ask for guidance. Make sure to describe what exactly you need help with.
Please note the OpenStreetMap project is on a voluntary basis. The project maintainer may take a while to get back to you.

Contributing map data can help in understanding the project structure. If you need any help with mapping, you can contact your local community at
https://openstreetmap.community/
or start a thread on
https://community.openstreetmap.org/

When testing application issues or your PR, it is important to test them locally, not on the live server. Such data does not belong in OpenStreetMap. See
osm.wiki/Sandbox_for_editing#Experiment_with_the_API_(advanced)

Those seem to be pillars in wall with gates, no bollards visible on Mapillary 2018.

osm.org/way/729909317/history
Dat is wel een kort segment met motor_vehicle=no, emergency=yes.
Pas verderop staat een access_sign node.
Ik verwacht de access-restrictie pas na de access_sign, behalve als de locatie van het toegangsbord is veranderd.

Horse farm here is maybe the one to the north

Another example, clearly horse farm

Ok, I see, this is building part. Needs resurveying / changing building outline if it is already finished construction.
osm.org/way/1346668756

osm.org/node/12455844550/history
seems at wrong location based on old Mapillary / Bing Streetside it is on the small building on the corner to the north
osm.org/way/1184249013

It might also be useful to add dog=leashed to the segment between the two gates.

osm.org/node/12456276754/history
Seems at wrong location. Use instead
https://api.panoramax.xyz/#pic=ffd55464-feae-4de2-9286-1bb5d1ed371d&focus=pic
sequence is more dense..

These are likely shelters/roofs for horses or similar?
They do not look like huts (or as Victor suggests, shooting cabins)

Ref osm.org/note/4493019

By changing the building outlines to building parts, there is no longer any building outline. As such no building will be displayed by (most) rendering applications.

Please resolve this as appropriate and comment on this changeset when you are done.
( note to other mappers: see
osm.org/user/googlenaut/blocks as to why user is being actively recommended to comment here.)

Hey crazed-mapper,

In reference to
osm.org/note/4518062

For private ways, you should use
access=private
The tag access=no is intended for areas prohibited to the general public, such as construction areas.

Hey MapCam,

Be careful when mapping objects obscured on aerial imagery.
Where available, you can use streetlevel imagery, though be aware it may be outdated.
('Edit' => right sidebar => Data Layers => i.e. Bing Streetside); solely for your information, proprietary (copyright) sources such as Google Maps etc. can not be used for this.
osm.wiki/Import/ODbL_Compatibility

It is best not to map these if not sufficiently visible.
osm.wiki/Verifiability

Instead, add a 'fixme' tag to request other mappers to survey the location.
osm.wiki/Key:fixme

Removed the unverifiable footway segment in
osm.org/changeset/165210839

Ref osm.org/note/4518858

'Standing stone put there with a crane' does not magically create (religious) anything for OpenStreetMap.
Religious landuse is reserved for points of interest (POI) providing i.e. religious services, offices(and if included with these, shops) to their users.
Places of worship are reserved for those which are/were used for religious practices by their users.
Neither, nor as such most objects, are intended for those used solely by a private individual, or inaccesible property without such proper reason to map them.

osm.wiki/Private_objects
(and links on each page)

The enclosed wooded area seems okay. It can at least kind of be seen to exist from sources contributors are allowed to use from the editor application (see 'Edit'); solely for your information, proprietary (copyright) sources such as Google Maps etc. can not be used for this.
The name should be the signed name, not description, see
osm.wiki/Names#Names_are_not_for_descriptions
(you already used description, which is good.);
though, some of the below recommendations apply here as well

I have removed the unverifiable standing stone and religious landuse. Resolved in

Hey green_leek,

Objects which represent a single group should be mapped as a single object if sufficiently close together.
See this page for more information
osm.wiki/One_feature,_one_OSM_element

(Some objects like charging points can be mapped individually, but usually have their own tag)

If there is a small gap, you can add a note tag saying there is one, but this is just so that other mappers do not add duplicates from aerial imagery.

These are foundations of demolished buildings, not ones for new to be constructed buildings.
Resolved in

Marked them as demolished and the area as brownfield.

There seems to be no physical signage for such a route at this location
https://api.panoramax.xyz/#pic=cb6b6972-9f29-4845-8b4a-2a242102a435&focus=pic
