On his hikes, one repeatedly finds signs of religious popular piety along the way, and (local or national) pilgrimage routes even lead there in a targeted manner. Often there are wayside crosses and wayside shrines, stations of the cross, but also chapels dedicated to various saints or the Virgin Mary are such popular places of prayer. Some Marian chapels have a specific reference, such as a "Lourdes" or "Fatima chapel".
The latter has its origin right here, because in Portugal there is this place called Fatima. It was there in 1917, during the Second World War, that the Virgin Mary appeared to three shepherd children several times. In the years that followed, Fatima developed into a large and important place of pilgrimage to Mary, far beyond the borders of the country. The Popes of the Roman Catholic Church (most recently John Paul II, Benedict XVI and Francis) have also made pastoral trips to Fatima. This sanctuary, the "Apparition Chapel", bears witness to the pilgrimage that is still active today.
