The Cruz de Ferro is many things to many people.
Is it 'recognised' historically, sacred, sanctified? No.
It is a fairly modern thing I understand.
Many pass it by with little more than a glance.
But for many, it has become a place of great significance and emotion.
The site itself 'triggers' these things in some way.
I don't think any form of 'beautification' is necessary or required. But what is done, is done.
I have visited four times so far, and will again, whatever they do to it.
I will utter my prayers and drop my stone and leave with tears in my eyes, whatever others may think of such 'nonsense'
PS, I usually time my visit to avoid the hordes, and have managed to do so thus far.
If it has to be at 2 am in future, to find peace and quiet. So be it
