We are still on the Portuguese Camino but yesterday we moved to the Spanish part of it. The two countries maintain the Camino in different ways. In Spain you see these posts a lot.

They always have the distance to Santiago on them. Here it is 151,560 kilometers. The Europeans use a decimal comma where we would use a period but more to the point: three places of accuracy? 151,561 would be one meter farther. Is that to the front door of the cathedral, or the alter, or the highest point on the roof? It just seems nutty to have this much accuracy. I wonder how the decision was made?
Also notice the little stones on top of the post (and a flower). We talked about the stones in an earlier post.
It is a tradition for Jews to leave stones on grave markers in cemeteries . No idea why, and probably in no way related to leaving stones on Camino way markers.
Just an interesting fact.
Could be related. Stones on grave markers is partially a way to honor the deceased and also to show someone has visited.
