Kiruna is only about a hundred years old. From a ramshackle bunch of shacks made from packing crates where the miners spent freezing winters and muggy summers, two little towns grew up. One architect-designed housing community was created very near the mining operations, at the base of the mountain of Kirunavaara. The other community was built across a lake on another hillside. This became the center of Kiruna, designed as a kind of utopian hill town, with a mix of wooden houses, winding streets, and stairways. Some of those utopian ideas didn't work out and already, with the advent of car and bus traffic, the growing city did away with some of the winding streets and built more typical, boxy and utilitarian mid-century sports halls and city buildings. Still, the city has been an interesting mix of old and new. From this spring, however, as a new Kiruna rises two miles away, the old Kiruna will begin to be abandoned.
