Nuclear bunkers for all: Switzerland is ready as international tensions mount

The shelters have become an integral part of the Swiss identity, on par with the country's famous chocolate, banks and watches.

In recent times the underground spaces have often been used for storage or as well-protected wine cellars. But they are being viewed in a new light since the war.

"People are discovering that Ukraine is very nearby," says Noth-Ecoeur, who heads civil and military security services in the mountainous southern Wallis region.

The wealthy Alpine country has pledged that each and every resident will have a shelter space if needed. The country of 8.6 million people counts nearly nine million spaces across 365,000 private and public shelters.

But while there are more than enough spots at a national level, there are vast regional differences. Geneva is worst off, with only enough places for 75 per cent of its
