Hey Learscail,

I would not recommend adding historical objects during your first edits, but you are welcome to do so.

Unfortunately, we can not use the SMR as sole source for adding objects. The SMR and layers available on the Historic Environment Viewer (HEV) are a proprietary/copyright source and OpenStreetMap does not have permission to use them.

In order to add these objects, you will need another source to verify they exist.

We have permission to use the following layers

- Layers available in OSM editors such as the one you are using.
(which I commented on earlier)

- NLS historic maps
https://maps.nls.uk/os/#ireland

- Esri World Imagery Wayback
(of which most current and oldest are available in the editor)
https://livingatlas.arcgis.com/wayback/#active=60013&mapCenter=-7.16811%2C52.61855%2C15

You can go outdoors and survey one to see if it is physically present, but most won't be visible (have been plough-levelled).
You can then add a source "survey" when saving your changes.

If you know or someone else knows about their existence you can add them with source "local knowledge of (myself, resident, employee, etc)" on saving your changes.

If there is a centuries old map/book in the library ('out of copyright') you can add the source as
"Book X, chapter Y, author Z"
(though this is preferably left to advanced contributors)

If you can't verify them in one of these ways, they are unverifiable and can't be added to OpenStreetMap.

KK024-011 is larger than mapped but the outermost ditch is only partially visible on aerial imagery.
It might not be quite circular.

For the enclosures in the meadows
KK024-159 might be visible on regular Esri but is deemed uncertain in SMR.
KK024-013001 is faintly visible.
KK024-013002 is clearly visible.
The enclosures in the meadows seem to be visible on regular Esri,
