Hi, hast du da evtl. einen Platzhalter-way vergessen zu löschen, mit dem du die Tags vorbereitet hast? Ich war zwar lange nicht dort, aber ein kurzes Stück Radweg auf der Elbwiese ist da meiner Erinnerung nach nicht.

shall I change it?

National Monument 536 is correct for the northern pair, also the wikidata, wikipedia-link, etc. - so basically everything except the location and the shape.

The southern ring seems not to be a national monument etc.

I checked the map of the Sites and Monuments Record here: https://heritagedata.maps.arcgis.com/apps/webappviewer/index.html?id=0c9eb9575b544081b0d296436d8f60f8

(search for "CO107-040" to jump to the location)

Turns out, both are sites with standing stones near Clodagh, one is a pair, the other (south) a ring of 5 stones plus some more stones.

More info here: https://mega-what.com/sites/Clodagh/index.html

So it looks like the original POI was correct (especially the circle form) and should get moved back (revert). Maybe it needs correction regarding the name/ID, and definitely the other stones (the northern pair) need a fresh POI.

Crosschecked sat images and streetview, it rather looks like the old position is wrong.
