The Trouée d'Arenberg is one of the most famous stretches of road in all of professional cycling. It's also one of the oldest; the cobblestones that make up the two-kilometre stretch of road were laid over a century ago, and due to Arenberg's popularity, the stones themselves have been known to be liberated by souvenir hunters from time to time.
That appeared to be the case this year, when cobblestones went missing on more than one cobblestone sector, potentially creating a major safety risk, as reported on by De Telegraaf.
