Calumet, the town copper built
Calumet was once the beating heart of the world's richest copper district -- a booming, polyglot town of immigrants. Today its grand old buildings anchor Keweenaw National Historical Park, and a quiet memorial marks the Copper Country's deepest tragedy.
It’s hard to believe today, looking at quiet little Calumet, that this was once one of the richest places on earth. Long before any of that, Native people mined copper in these hills for thousands of years. Then, in the 1860s, a copper-bearing rock formation was found here. The Calumet and Hecla Mining Company grew up around it. It became the single largest copper producer in the country — a Boston-owned giant that some called the richest metal mine on earth. It paid its shareholders more than seventy million dollars over the years, the equivalent of a billion today.
The mines drew people from all over the world. By 1900, fully ninety percent of Calumet’s residents were foreign-born. They were Finns, Cornish, Italians, Croatians, Slovenians, Swedes, and more. Often they couldn’t speak to one another except through the work they shared. They built a town to match the money: an opera house, grand churches, stone commercial blocks. It was all far bigger than a place this size would otherwise have. Much of that architecture still stands, remarkably intact. That is exactly why Calumet was chosen as the centerpiece of Keweenaw National Historical Park. The old Calumet and Hecla offices are now the park’s headquarters. You can walk the historic downtown, tour the Calumet Theatre, and visit heritage sites that tell the copper story.
Calumet also holds the Copper Country’s deepest sorrow. On Christmas Eve 1913, during a long and bitter miners’ strike, families gathered for a holiday party upstairs at the Italian Hall. A reported cry of “fire” sent people toward the stairs, although there was no fire. The National Park Service’s dedicated memorial account says 73 people died, 59 of them children, and it cautions that parts of the event remain debated. The hall is gone now. Its original stone arch stands in a memorial park on Elm Street beside a monument naming those who died. It is a quiet place to remember them and the families behind the Copper Country’s labor history.
