Love locks are commonplace in a growing number of countries (although less so in the UK from what I've seen). Romantic couples will write their names, and often the date, on a padlock and attach it to a public space, usually a fence or a bridge. At this location, there was a large number of these, mostly likely due to the fantastic view over Golfo di Napoli and on towards Mount Vesusvius in the background.
I wanted to get a nice close up of the locks, but also give you a sense of where and why. Please excuse the pun in the title, I couldn't resist it!
