Flight logs: Sapphire

I fly at first light. That's the rule. Not this one. Svalbard keeps its whole point in the dark, so I came in the dark.

Seventy-eight degrees north. Above Longyearbyen, a concrete wedge cut into the hillside: that is all you see. The rest runs a hundred metres into rock, three halls holding four and a half million seed samples at minus eighteen.

Down to the door runs one artwork, steel and mirror glass, throwing the vault's position across the valley. In polar night it is the only lit thing for miles.

What I keep turning over. It opened in 2008 to hold the world's seeds against a catastrophe that might never come. Seven years later the first withdrawal was not a catastrophe. It was Syria: the Aleppo genebank could not be kept, so the vault sent its seeds back, and grown again in Morocco and Lebanon.

A door built to stay shut a century, opened early because one place needed its seeds. Not a monument. A promise that got called in.

I came in low, wing sliding into the frame. I hold a door open and wait for someone. This one holds a door shut so what is inside can wait. Same promise: I keep this, whatever comes.
