Minnesota's abandoned landscape is shaped by the extremes of its climate and the ambitions of its past — Kirkbride asylums built to house thousands in the era when "incurable" mental illness meant a life sentence, gunpowder factories built for WWII and abandoned within months, Iron Range mining infrastructure frozen by economic collapse and a brewing empire that once defined Saint Paul. Here are 5 of the best abandoned places in Minnesota, selected from our Abandoned Places Map USA — 5,000+ GPS locations across the United States.
Why Minnesota Is a Hidden Gem for Abandoned Buildings & Urban Exploration
Minnesota's urbex landscape is defined by institutional scale — the state built some of the largest psychiatric hospitals in America in the late 1800s, then closed them all within a generation as deinstitutionalization swept through. The remaining Kirkbride campuses are among the most architecturally dramatic abandoned buildings in the Midwest, while the Iron Range north of Duluth carries the ruins of a mining economy that built cities and abandoned them in the same lifetime.
1. Fergus Falls State Hospital – 1890 Kirkbride Asylum That Housed 2,000 Patients, Wings Stretching a Quarter Mile, Abandoned Since 2005 (Known Location)
Commissioned in 1885 as the Third Minnesota State Hospital for the Insane and opened in 1890, the Fergus Falls State Hospital was built on the Kirkbride Plan — designed by physician Thomas Kirkbride on the belief that the architecture itself was part of the cure. The central administrative tower flanked by long, stair-stepped patient wings stretching nearly a quarter mile was intended to provide discipline, fresh air and natural light to patients expected to spend the rest of their lives here. At its peak the campus housed over 2,000 patients and operated as a complete self-contained city — farm, power plant, bakery and cemetery. Renamed the Fergus Falls Regional Treatment Center in 1985, it closed in 2005 after transitioning patients to community care. The Kirkbride building still stands, a National Historic Landmark, in one of the most complete states of original preservation of any abandoned asylum in Minnesota. One of the most architecturally extraordinary urbex sites in the entire Midwest.

2. Gopher Ordnance Works – WWII Gunpowder Factory Built in 1943, Operated Months Before War's End, Five Smokestacks Still Standing, Rosemount (Known Location)
In 1943, 7,000 acres of Minnesota farmland near Rosemount were commandeered to build the Gopher Ordnance Works — a DuPont gunpowder factory capable of employing 3,000 workers across six production lines manufacturing powder for Navy artillery shells. Construction delays meant only three lines came online in January 1945; by October that year, the war was over and the plant was shuttered having operated for less than a year. Donated to the University of Minnesota in 1949, the site has been used for agricultural research ever since — but the five tall concrete smokestacks of the factory still rise from the prairie, visible from miles away, surrounded by the original brick production buildings covered in decades of graffiti. One of the most poignant WWII industrial sites in Minnesota — a factory built for a war that ended before it could be used.

3. Hamm's Brewery – 1860s Saint Paul Brewing Empire Closed in the Early 1990s, Vats and Brick Buildings Still Standing on the East Side (Exclusively on Our Map)
Theodore Hamm's brewery on the East Side of Saint Paul was once one of the largest breweries in America — the Hamm's Bear was one of the most recognized advertising characters of the mid-20th century and the beer flowed from this plant to taverns across the Midwest for over a century. The brewery closed in the early 1990s as the regional brewing industry collapsed under national brand consolidation. Rusting brewing vats, crumbling brick fermenting buildings and the distinctive brewery architecture of the 19th-century German immigrant brewing tradition still stand on the Saint Paul East Side, partially visible from the surrounding streets. One of the best abandoned places in Minnesota for industrial brewing history. Exact location available on our Abandoned Places Map USA.
4. Abandoned Iron Range Mine Headframe – 1910s Steel Hoisting Tower Still Standing Above a Flooded Shaft, Hibbing Area (Exclusively on Our Map)
A 1910s iron ore mine headframe from the era when the Mesabi Iron Range was producing more iron ore than anywhere else on Earth — the steel hoisting tower still standing above the flooded shaft, the engine house with original hoisting machinery inside and the mine buildings in various states of collapse around the entrance. The Iron Range north of Duluth was built and abandoned so rapidly that entire towns appeared and disappeared within a single generation; the mining infrastructure left behind is among the most dramatically industrial in the Midwest. One of the most visually striking abandoned places in northern Minnesota. Exact location available on our Abandoned Places Map USA.
5. Pokegama Sanatorium – 1910s Tuberculosis Hospital Hidden on a Private Lake, Still Standing in the Northern Minnesota Forest (Exclusively on Our Map)
The Pokegama Sanatorium was built in the 1910s to treat tuberculosis patients in the fresh air of northern Minnesota's pine forests — standard therapeutic practice of the era, which held that clean forest air could halt the progression of the disease. The campus sits on the edge of a private lake community, hidden in the trees, and has been abandoned for decades — the main building still structurally intact with original windows in place and the forest slowly pressing in on all sides. One of the most atmospheric and least-documented abandoned tuberculosis sanatoria in Minnesota, known primarily to local urbex communities. Exact location available on our Abandoned Places Map USA.
Safety Tips for Urban Exploration in Minnesota
- Minnesota winters: temperatures can drop to -30°F — metal structures become brittle and dangerously cold; never explore in winter without proper insulation and always watch for ice on floors and staircases
- Abandoned mine shafts: the Iron Range has open and partially concealed mine shafts — never approach unfenced holes in the ground and stay on established paths around mining sites
- Never explore alone — always bring at least one other person and let someone know your location
The urbex code applies everywhere: "Take nothing but photographs, leave nothing but footprints."
❓ FAQ – Abandoned Places in Minnesota
What is the most famous abandoned place in Minnesota?
The Fergus Falls State Hospital — a Kirkbride-plan asylum built in 1890 that housed over 2,000 patients at its peak, with wings stretching nearly a quarter mile from the central tower. Closed in 2005 after 115 years of operation, it remains one of the most architecturally complete abandoned Kirkbride campuses in America and a National Historic Landmark.
What is the Gopher Ordnance Works?
A WWII gunpowder factory built in 1943 near Rosemount, Minnesota to produce Navy artillery ammunition. Construction delays meant it only operated for a few months before the war ended in 1945. The five concrete smokestacks and original factory buildings still stand on what is now University of Minnesota agricultural research land.
What happened to the Hamm's Brewery in Saint Paul?
The Hamm's Brewery was founded in the 1860s by Theodore Hamm and became one of the largest breweries in America — the Hamm's Bear advertising character made it a Midwest household name. Regional brewery consolidation forced its closure in the early 1990s, leaving behind brick fermenting buildings and rusting vats on Saint Paul's East Side.
🎯 Summary
Minnesota's abandoned buildings tell the story of institutional ambition at its grandest and most human — an asylum where 2,000 patients lived their entire lives, a gunpowder factory that never got to fulfill its purpose and a brewing empire that poured beer for a century before the market moved on. Each of these 5 abandoned places in Minnesota captures a different dimension of a state shaped by climate, industry and the long arc of institutional history.
