Hibbing High School is a public school, grades 7–12, in Hibbing, Minnesota, United States. It was built from 1920 to 1922 as the entire city relocated two miles (3 km) south to make way for the expanding Hull–Rust–Mahoning Mine. The lavish Tudor Revival building was constructed at a cost of about $3.9 million (equivalent to $56,971,096 in 2022), becoming known as the "castle in the woods" and—thanks to its polished brass fixtures—the "school with the golden doorknobs". The project was bankrolled by the mining industry, which wanted to make the move more palatable for those being displaced. It also satisfied immigrants' desire for their children's education.Hibbing High School is listed on the National Register of Historic Places. Visitors may tour the building on their own during the school year or on guided tours during the summer. Source : Wikipedia (en)
