Design story behind memorial for Madrid train bombings

Metropolis magazine has a beautiful photo-feature about the design story behind a memorial for victims of the 2004 train bombings in Madrid: Link (Thanks, Susannah / via La Petite Claudine!)

Reader comment: Scott Andress says,

A few months ago we visited the M-11 memorial in Madrid. It was a very
moving experience and the memorial design is striking. If you're
interested, we have some photos posted on flickr from our Madrid
podcast.

I have a few additional photos on my personal flickr profile: Link

Pictures just don't depict the atmosphere completely. It is a place
that must be visited in person to fully appreciate.
