At both spots (here and the one Pleiades suggests) based on imagery seem to have some ruins. This spot, the node ( https://www.openstreetmap.org/node/10614065190/history ) seems to have originally be mapped as cemetery of 4th century, before it changed to the sanctuary, so maybe here is a cemetery and the other spot may indeed be the sanctuary. In theory, someone should go there and check (and try figure out themselves because I doubt there will be any signage).

I'm aware of Pleiades and of how accurate it depicts the locations of various ancient sites (for most of them if not all, haven't really checked some items) based on the references.
