As Kocio noted “notes” are not markers. Notes are used for indicating mistakes in the map.
You can create links pointing to 1 position (marker) on the map.
If you need more markers to show up at the same time, you should consider using something as http://umap.openstreetmap.fr
It would even be better that you map all the items that are visible today. Maybe there are information boards, memorials etc that can be added to the map.
