Within the Arctic Circle in the northernmost part of Sweden lies the mining town of Kiruna, where a $2bn project is currently under way to save no fewer than 3000 buildings. As extractions of iron ore have moved increasingly closer to Kiruna, the ground beneath the town grows unstable and will eventually cause its foundations to collapse. In efforts to prevent the town from sinking, it will be moved two miles (3km) to the east. June 2016 marks the two-year anniversary of the commencement of Phase One of the relocation, which will take place over three phases and span 20 years. During the relocation, buildings will be moved whole, or disassembled and reconstructed to sit beside new ones.
