Take a look at the underground bunkers and shelters that were made to prepare Switzerland for war
When it comes to describing the Swiss' determination to prepare for the worst case scenario, no idiom rings truer than: "In time of peace, prepare for war".
Of course, Switzerland hasn't been engaged in a military conflict for over 150 years, but hidden beneath the country's surface is a vast network of military bunkers and fallout shelters that exist to protect the Swiss people from potential onset of war and nuclear devastation.
Although the exact number of military bunkers is not known, a common estimate is that there are around 20,000 bunkers dotted around Switzerland to thwart any oncoming army.
Add that to the near 310,000 private and public fallout shelters and you have a country that can potentially protect all of its 8 million citizens from nuclear war, making Switzerland the most prepared nation in world for this destructive scenario.
A photographer calling himself Kecko has chronicled some of the most interesting bunkers and shelters in Switzerland, here's a few of our favourites:
The dormitories for civilians do look a bit more inviting than the military's sleeping quarters.
Switzerland's obsession with fallout shelters stems from the cold war and the looming threat of nuclear war. After the Cuban missile crisis, the country passed the first laws for the creation of fallout shelters in 1963.Swiss Civil Defense Bunker, Berneck
This may look like a giant "Thunderbirds" type camouflaged doorway, but this is actually part of the bunker's ventilation system.
Although the size and extent of this bunker facility has not been revealed, many bunker tours still pass through here to marvel at Switzerland's feats of engineering and ingenuity.
Perhaps Switzerland's greatest strength doesn't come from having a huge army or arms, but the psychological effect on any potential invaders to doubt every rock, cave or mountain top as positions for Swiss military.
This entire mountain top is under the control of the Swiss army as a secret bunker complex, serviceable by cable cars.
This giant bunker was built between 1970 and 1976 at a cost of 40 million Swiss francs. If it ever had been needed, two motorway tunnels would have been sealed by four 350-ton gates, with room enough for 20,000 beds and hundreds of toilet cabins - in fact one third of the population of Lucerne would have found shelter here inside Mount Sonnenberg.
