To be honest, there are plain, asphalt roads here in Odense. But many of the streets, and most of the bicycle roads are cobblestone.
Or, to be accurate, "sett" roads. I did some research on this. A little history of the cobblestone. The things you learn by reading!
Cobblestones are stones that were frequently used in the pavement of early streets. The word "cobble" means "rounded lump", originally any small stone rounded by the flow of water; essentially, a large pebble. It was these smooth stones that were gathered from stream beds that paved the first "cobblestone" streets.
A real Cobblestone Road
A "sett" is a rectangular quarried stone used for paving roads, usually made of granite. A cobble is a naturally occurring round stone.
So, when you think you see a cobblestone road, more than likely, its a sett road!
I have noticed in my walks and bicycle rides that there are many kinds of cobblestone patterns. (I know, sett, but old habits die hard!)
A little more research and I found out there are four basic patterns: Random. Coursed, Fan, and Bogen.
Random is, well a random pattern (duh!) It is the cheapest to lay and not as aesthetically pleasing as other patterns
Random
Laying a "Course" road.
Fan is a very decorative pattern, requiring more craftsmanship.

Regardless of the reasons why they are installed, they certainly are beautiful.
No more history lessons folks. I think I will take a ride on the cobblestone bicycle street just outside. (I know, I know, sett street. I think I'm sticking to cobble).
