Bahnhof is a Swedish Internet provider. Their service is probably great, but their office is definitely wonderful. Honestly, it looks a whole lot like a Dharma Initiative building from Lost. The office, designed by Albert France-Lanord (A)rchitects, is built into a former anti-atomic shelter in Stockholm.
The walls are the natural granite of the Vita Berg Park. The office somehow manages to feel ominous, modern, and naturalistic at the same time. And best of all, in the event of nuclear holocaust, it looks like Sweden will still have Internet.
