There’s a neat question mark, about 11m tall, drawn on the
ground of a construction site in the city of Rennes, France.

Of course, the question about this question is: why is it
there?

The “?” appears to be made out of grass, perhaps by removing the
turf around it. However, in http://www.panoramio.com/photo/2119407 this photo of the
construction site there is curved paving to the bottom left which
could correspond to the area of the question mark.

I also found http://assoalphonseguerin.free.fr/article.php3?id_article=107
these pictures which might be of the same area, but they don’t
provide many additional clues.

So, I’m turning it over to you, our sleuthing readers, to solve
this mystery! Any ideas?

Thanks to Julien Balas
