The fascinating city relocation project in Kiruna, Sweden, reaches a new milestone as the iconic Kiruna Church is moved in one piece.

The mammoth move has seen the wooden structure, weighing over 600 tons, transported on specialized trailers traveling at about 1,600 feet per hour.

With great fanfare, a historic red wooden church considered one of Sweden's most beautiful buildings began its slow move from its home in the Arctic town of Kiruna on Tuesday to allow the expansion of Europe's biggest underground mine.
