It's not the gradient that makes this so tough, it's the fact that the road is made up of large irregular stones. It makes for an odd sensation as your front wheel bobbles up and down. A short climb but I imagine very difficult in the wet. Harder though would be to race down the cobbles on the other side.
Right on the French/Belgium border, the area is steeped in wartime history, horrendous battles were fought here.
