St. Louis County is Minnesota’s largest county by area, stretching from Lake Superior’s shore to the Canadian border. Established in 1855, its county seat, Duluth, is a major port city known for its shipping, universities, and thriving tourism. Other notable communities include Hibbing, Virginia, Eveleth, and Ely. The county’s geography is diverse—lakes, forests, and the Mesabi Iron Range define its landscape. Historically tied to iron-ore mining, it’s now supported by healthcare, education, and outdoor recreation. Housing varies dramatically: urban condos and historic homes in Duluth, modern suburban developments, and remote lake cabins in Ely or Cook. The region mixes urban, suburban, and rural living. Average home prices are around $320 k–$420 k, but Duluth neighborhoods and lakeside homes can surpass $600 k–$900 k +. New construction averages $375–$425 per sq ft, higher for custom or remote builds. St. Louis County offers everything from city amenities to wilderness serenity, making it one of Minnesota’s most geographically and culturally diverse regions.
