From my visit to the sprawling iron ore mines at Luossavaara-Kiirunavaara in Swedish Lapland. Before the tour, I’d been meaning to experience the mine for almost 35 years, which is when I visited Kiruna for the very first time on my way to Riksgränsen. The mine tour offers a mindboggling experience, for sure. On any given day of the year, the mining company, state-owned LKAB, excavates enough iron to produce six full-sized Eiffel Towers.
