New Hampshire is New England's most mountainous state — and its abandoned landscape reflects the industries the White Mountains built and then abandoned. A French-inspired castle built by an eccentric New York costume designer, gutted by fire in the 1960s, its staircase rising into open sky. Abandoned textile mills along the Merrimack River. WWII mountaintop observation posts. Here are 5 of the best abandoned places in New Hampshire, selected from our Abandoned Places Map USA — 5,000+ GPS locations across the United States.
Why New Hampshire Is a Hidden Gem for Abandoned Buildings & Urban Exploration
New Hampshire's urbex landscape combines New England's industrial heritage with the White Mountains' unique history of resort tourism, military use and agricultural abandonment. The state's compact geography concentrates textile mill ruins, Victorian summer hotel ruins and Cold War military infrastructure within a single day's drive of each other.
1. Madame Sherri's Castle – 1930s French-Inspired Party Mansion, Gutted by Fire 1962, "Staircase to Nowhere" in the Chesterfield Forest (Known Location)
Antoinette Sherri was a New York theatrical costume designer who built a summer estate in the woods of Chesterfield in the early 1930s — a whimsical French-inspired stone structure with arched windows and a grand exterior staircase, used for elaborate parties attended by the theatrical set. When her finances collapsed she lost the estate, which sat vacant and deteriorated until a fire gutted the interior in 1962. What remains is one of New England's most dramatic ruin photographs — the stone staircase rising from the forest floor to an open sky where the second floor once was, the arched stone walls standing and the surrounding New Hampshire forest pressing in from every side. Accessible via a short trail in Madame Sherri State Forest. One of the most iconic abandoned places in New Hampshire.

2. Abandoned Merrimack Valley Textile Mill – 1830s-1850s Industrial Canal Mill with Original Brick Construction, Manchester Corridor (Known Location)
Manchester was the largest planned industrial city in America when the Amoskeag Manufacturing Company built its mills along the Merrimack River in the 1830s-1850s — a complete company city of mill buildings, worker housing and canals covering a mile of riverfront. When Amoskeag went bankrupt in 1935, the largest textile company in the world simply closed overnight. Several original mill buildings still stand in various states of abandonment alongside those that have been converted — the 1840s brick construction, the mill canal system and the scale of 19th-century industrial ambition make this one of the most architecturally significant abandoned places in New Hampshire.

3. Abandoned White Mountains Summit Hotel – 1870s Victorian Summit House, Foundation and Ruins Still Visible, Mount Willard Area (Exclusively on Our Map)
A 1870s-1890s Victorian summit hotel from the height of White Mountains resort tourism — when rail access made New Hampshire's peaks a fashionable summer destination and entrepreneurs built hotels on every accessible summit. When the automobile changed travel patterns and the carriage roads were abandoned, the summit hotels became economically unviable. Foundation stones, stone walls and the collapsed timber framing of the main structure still mark the summit location, the panoramic views unchanged from the era when hotel guests watched the sunset from the dining room. One of the best abandoned places in New Hampshire for Victorian mountain resort archaeology. Exact location available on our Abandoned Places Map USA.
4. Abandoned New Hampshire Mica Mine – 1890s-1940s Sheet Mica Extraction Site with Headframe and Waste Pile, Grafton County (Exclusively on Our Map)
New Hampshire's White Mountain foothills contain dozens of abandoned mica mines from the 1890s-1940s — mica was essential for electrical insulation before synthetic materials replaced it. A Grafton County mine retains the headframe still standing above the shaft, the open pit where sheet mica was extracted by hand and the waste pile of discarded pegmatite glittering in the New Hampshire forest. One of the most unusual and least-documented abandoned places in New Hampshire — industrial archaeology of a mineral most people have forgotten was once strategically essential. Exact location available on our Abandoned Places Map USA.
5. Abandoned New Hampshire Hill Farm – 1850s-1880s Hill Farm with Stone Walls, Cellar Hole and Orchard Still Producing, Sullivan County (Exclusively on Our Map)
A 1850s-1880s New Hampshire hill farm abandoned when the family moved west or down to the mill towns — the cellar hole still intact, the stone walls running through the second-growth forest and the original apple orchard still producing fruit from trees planted 150 years ago. New Hampshire's hill farm abandonment began in the 1840s when western farmland opened; by 1900 thousands of upland farms had been abandoned. The combination of cellar holes, stone walls, old orchards and returning forest creates the distinctive New Hampshire landscape of recovered nature layered over human history.

Safety Tips for Urban Exploration in New Hampshire
- White Mountains weather: conditions change rapidly at elevation — always carry rain gear, warm layers and a map when hiking to any mountain ruin site; Mount Washington has recorded the highest wind speed in the Northern Hemisphere
- New England winters: ice and snow make mill sites and forest ruins dangerously slippery November through April — wear non-slip footwear year-round
- 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 New Hampshire
What is the most famous abandoned place in New Hampshire?
Madame Sherri's Castle in Chesterfield — a 1930s French-inspired stone estate built by New York theatrical costume designer Antoinette Sherri, gutted by fire in 1962 and now reduced to a dramatic staircase rising to open sky in the Chesterfield forest. Accessible via a short trail in Madame Sherri State Forest.
What happened to the Amoskeag mills in Manchester?
The Amoskeag Manufacturing Company was once the largest textile company in the world — its mills along the Merrimack River in Manchester employed 17,000 workers at their 1910s peak. When the company went bankrupt in 1935, it simply closed overnight. Several original 1830s-1850s mill buildings still stand along the Merrimack in various states of preservation and abandonment.
Why are there so many abandoned farms in New Hampshire?
New Hampshire's upland farms were marginal at best — the growing season was short, the soil rocky and the terrain steep. When cheap western farmland opened after the Civil War, New Hampshire hill farmers moved en masse to the Midwest or down to the mill towns. By 1900, vast areas of upland New Hampshire had reverted to forest, leaving thousands of cellar holes, stone walls and old orchards across the state.
🎯 Summary
New Hampshire's abandoned buildings range from an eccentric costume designer's stone staircase to nowhere, to the ruins of the world's largest textile company and Victorian summit hotels whose foundations still mark New Hampshire's mountain peaks. Each of these 5 abandoned places in New Hampshire captures a different layer of a state shaped by mills, mountains and the remarkable things that get left behind when both industries move on.
