BBC News - Dark Matter: Experiment to shed light on dark particles, Feb 06, 2013

 "In a man-made cavern, deep beneath a mountain, scientists are hoping to shed light on one of the most mysterious substances in our Universe - dark matter.
The Gran Sasso National Laboratory seems more like a Bond villain's lair than a hub for world class physics.
It's buried under the highest peak of Italy's Gran Sasso mountain range; the entrance concealed behind a colossal steel door found halfway along a tunnel that cuts through the mountain."
