Wrapping itself around the Millénaire shopping centre and inside the V of two stretches of canal, in the most part the address is little more than a footpath. Paris apparently cuts half-way through the allée, but readers from last year will surely be pleased to know that the bright red bridge does now offer direct access to and from the city.
There remain no street signs along the arteries labelled 'Allée Guy Debord' in the map above. Instead, the sign below was found just at the point where the thin black line - a genuine footpath - begins.
Further along there is a second, before the footpath ends in a complete dead-end. New housing borders the allée, but I'm not sure who lives here. This part of Aubervilliers has become a centre of Chinese wholesale traders, and a Chinese family were sitting on a wall, quietly observing me whilst I took photos of their street sign.
They must have wondered exactly what I was doing - and why I was smiling. It was though not just a mystery solved but also exactly what an address named after Guy Debord should look like.
