One of the great experience, especially for non-Catholics, is to visit a pilgrimage church.
And if you do such in an Italian or Spanish speaking .... or especially in the Americas, it's even more interesting.
So I went to ...
, wrong photo, I went to ...
.... the "Lourdes of America", "the most important Catholic pilgrimage center in the United States" ...
... to
El Santuario de Chimayo.
[Again: no photos inside ...]
