Residents of Kiruna, a small city of 18,000 people located north of the Arctic Circle in Sweden, have been gradually moving their entire town for more than 20 years. This relocation is due to ground subsidence caused by the nearby LKAB iron mine. Since 2004, over 3,050 homes and nearly 200,000 square meters of buildings have been moved about three kilometers from their original locations. In 2025, the city's historic wooden church, built in 1912 and weighing 672 tonnes, was transported five kilometers at a cost of over 44 million euros. The new town center, which began taking shape in 2022, is expected to be fully completed by 2035. Kiruna was founded at the end of the 19th century around a rich iron ore deposit known as Kiirunavaara. This deposit is 4 kilometers long, up to 120 meters thick, and extends more than two kilometers deep. LKAB, the company that has been operating the mine for over a century, has extracted more than 950 million tonnes of ore, but only a third of the original deposit has been mined. This suggests that mining operations could continue for several more decades. The extraction method used, called sublevel decline blasting, involves creating underground voids as ore is removed. These voids gradually rise, causing the ground above to sink, which has led to the need to relocate parts of the city. Among the many buildings affected, the Kiruna wooden church has drawn particular attention. Built in 1912, it is considered one of Sweden's most beautiful religious buildings. Rather than demolishing it and rebuilding a replica, LKAB decided to move the entire structure intact. The operation involved lifting the church onto large trailers with specially designed wheels. The convoy traveled nearly five kilometers at a slow pace, with thousands of people watching the event. The cost of this single move exceeded 44 million euros, and was fully covered by LKAB. The new town center, located three kilometers east of the original town, has been under development for several years. The new town hall was completed in 2018, and the entire new center was inaugurated in 2022. So far, 41 buildings have been moved in blocks rather than demolished, preserving the architectural history of the city. This approach reflects Kiruna's effort to maintain its identity while adapting to the challenges of relocation. The project, which must continue until 2035, shows how the city is reinventing itself while keeping tangible links to its mining past and its Arctic heritage.
