This was the scene of desolation that greeted Aalto when he was commissioned by the Association of Finnish Architects to reconstruct the town in 1945. “He saw the burned town as an opportunity,” says Jussi Rautsi, a former planner and researcher at the Alvar Aalto Foundation. Partly inspired by the US president Franklin Roosevelt’s Tennessee Valley Authority, Aalto created a plan for all of Lapland – a land mass as large as Holland and Belgium combined.

Aalto started by rebuilding the city with single housing units designed specifically for the climate in Rovaniemi and Lapland so they had as little north-facing facade as possible, and maximum external exposure to the sun in the south-west. In the 1950s his plan expanded beyond the city to include the entire region.

Aalto factored in hydroelectric plants being built on the great rivers of Lapland, and commissioned impact assessments to see what the effect would be on the environment, indigenous Sami, reindeer herds, water basins and microclimate. “Nobody in the world had done such a plan,” says Rautsi. “It had all spatial levels: regional, entire town, parts of towns, neighbourhoods, even peripheral estates. This was the only plan of this magnitude in the world.”

But Korvatunturi is remote and almost inaccessible: more than 200 miles to the north of Rovaniemi, which already had an airport.
