The Super-K is a neutrino observatory in Japan; it is 1000 meters underground, contains a lake of 50,000 tons of pure water & every inch of the the 41 meter high walls are lined with over 11,000 photomultiplier tubes. It is also one of the most amazing man made objects I've ever seen images of. Super high res photos available here. More photos of the construction & recent restoration. Via.
