The Heart of the Shrine is part of the whole experience at Fatima, but it is a very important part. Because of that, it is where most of the people are gathered, always the busiest area, seating is limited, yet this is where most people pray. It is where the public can attend the open air masses daily, which we did, and items bought there to take home, religious art, etc. is blessed. I felt the unity with the other worshippers and was thankful for the spiritual blessings received. For a more personal spiritual, much more quiet moment, one that I received joy, was visiting the other places where the children saw Mary elsewhere (Loco do Anjo and Poco do Arneiro). See my reviews of those also. If you get the opportunity, hope you can visit Our Lady of Fatima in Portugal.
