To save a city from its own iron mine, Sweden is moving it entirely.
In short: Kiruna, Sweden’s northernmost city, was built to serve a massive iron ore mine. Today, that same mine is causing the ground beneath the city to subside. To survive, the entire town is being relocated three kilometers east, a monumental engineering project that includes moving historic buildings and infrastructure.
Founded in 1900, Kiruna grew rapidly around the Luossavaara-Kiirunavaara Aktiebolag (LKAB) mining operations. The city’s development was revolutionary for its time, with architects Per Olof Hallman and Gustaf Wickman designing the town to mitigate the harsh sub-arctic climate. By 1930, the population had surged to 12,884, and the city became a vital hub for Swedish industry. Throughout the 20th century, Kiruna’s identity was inextricably linked to the iron ore extracted from the Kiirunavaara and Luossavaara mountains, which proved essential to the German war machine during World War II and later fueled Sweden's economic diversification.
The necessity for relocation stems from the physical reality of underground mining. As the Kiirunavaara mine expanded, it began to undermine the stability of the land upon which the city center sits. In 2004, officials formally decided that the municipality’s core would need to be moved to prevent collapse. This process is not merely about building new structures; it involves the careful relocation of significant landmarks, including the city hall and the historic church. The new site, situated northwest at the foot of the Luossavaara mountain near Lake Luossajärvi, was proposed in 2007.
The scale of this urban transformation is unprecedented. Work began in November 2007 with the installation of a new main sewage system, followed by the development of detailed urban layouts. These plans incorporate modern travel centers, artificial lakes, and the integration of the Luossavaara hill into the new city fabric. While the project is a response to the risks posed by mining-related subsidence, it also represents a rare opportunity to redesign an entire city from the ground up, balancing the industrial heritage that created Kiruna with the modern needs of its 23,167 residents.
