The altar, with a nice, simple Roman dignity to it -- the only thing that might add to this would be the use of reliquaries in place of the flowers (though this is not to be taken as a critique let it be known).
A second post by Hilary White details more about the pilgrimage, St. Winifrede's and the Holy Well itself:
For those of us with English and Catholic heritage in our veins, can there be more consoling a sight than the display of the Catholic religion in the public English sphere, via processions, the sight of velvet Roman copes, incense and the Blessed Sacrament?
