Shrines Religious and Secular

It seems everywhere in Italy there are shrines - my favorite are the almost spontaneous roadside ones. They all seem to be well-maintained, with flowers, candles and offerings at each one. Most are to Mary, and some are for specific saints. I haven't taken pictures of all of them, but just a few that caught my eye or when I had my camera handy.

Saint Anthony of Padua!

San Severino

And then there is, apparently, an Italian fascination with Snow White. A lot of shops (touristy and non-) have Snow White things, but there are actual Snow White garden gnomes. And in more than one place - Castelraimondo and Capri. That seems far enough apart not to be related unless it's a bigger cult of interest. Just one question: why?
