It’s a Mystery

Wednesday, 24th October 2007 by

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 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 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?
