Have you heard of the Via dell'Amore? That translates to Pathway of Love, and it's a path linking two of the villages that make up Cinque Terre, Manarola and Riomaggiore. As you might expect, it's breathtaking and totally romantic - Greg and I celebrated our 2nd anniversary here and I am certain that won't be the last time we have an anniversary in Cinque Terre.
It's a trend in Europe to put locks on bridges, rails, cables, etc in romantic places to commemorate your love, so of course the Via dell'Amore is covered in them. Here's a little background info on the path if you're interested.
