Kiruna, in the far north of Sweden, exists because of an iron ore mine, and is now moving out of the mine’s way. The ore body runs at a slant down under the old town, and the deeper the mining goes, the more the ground above it cracks and sinks, so the town centre is being rebuilt a few kilometres east, one building at a time. In August 2025 the town’s wooden church, all 672 tonnes of it, rode there on remote-controlled trailers at about half a kilometre an hour, over two days. The mining company paid for the move. It had also paid for the church in the first place, in 1912, and handed it to the parish as a gift. So the same company built the church on top of its ore, and a century later carried it gently away from the hole it was making.
