Yes, I know these apparitions. But I have many doubts that it is a true apparition. In Spain it is very well known.
Some people I know strongly believe in this apparition. But I think there have been allegations of fraud in this case. Some high donations that left some people without family assets. Very controversial.
I know about this one too and have wanted to go there for years. I know several people who have been and received Graces - in fact, a friend was supposed to go a few months ago, I forgot to ask her about it. I 've read a few books about it too, interviews with the seer and the messages and believe that it is authentic. There has been a real fight there, much of it with civil authorities I believe over the use of the land. The fight reflects the spiritual struggle.
