People who visit here (of which I assume there are none) will know that I occasionally rant about how cool bomb shelters are. Dad put me onto this excellent article about the Swiss:
Under Swiss law, local governments are required to provide shelter spaces for everyone, and in the early 1970s Lucerne was short by several thousand. The new Sonnenberg motorway tunnel, just being built, seemed a neat solution: kit it out as a nuclear shelter as well and it could hold 20,000 people.
The monstrous Sonnenberg shelter though, is being gradually dismantled. But not because it has finally been deemed unnecessary: no, no, the real problem is those 350 tonne blast doors. When they were tested, they would not shut.
Yet another stop on my eventual bomb shelter tour of the world.
