One of the first things I noticed on my trip to Boulogne were these fish stencils painted on the pavements and pedestrian crossings. As well as providing an interesting talking point about the town, they also serve a purpose in directing tourists to the major attractions like the Old Town and the Castle.
On my last day, as I walked over to the port to wait for my coach back to the UK, I noticed that some creative local had taken artistic license on one of the fish (below). It certainly made me giggle.

Having these fish all over town leading tourists to sites is a fabulous idea!! Saves the locals from always having to give directions!
Definitely! Maybe we could use the idea in other towns. Here in Cardiff, for example, we could have little Welsh dragons directing people. What would you have in your home town?
