The House on the Rock in Wisconsin contains a room filled floor-to-ceiling with carousel animals—not one carousel, but hundreds of carved horses, camels, and mythical creatures stacked so densely you can barely walk through. Nobody asked for this. One man, Alex Jordan Jr., decided the world needed it anyway, and now it exists.
That’s the thing about the best small museums in America. They exist because someone cared obsessively about something most people would walk past. These aren’t the grand institutions with marble steps and corporate sponsors. These are the museums built around mustard jars, toilet seat art, and things that make you say “wait, there’s a whole museum for that?” They’re scattered across the country in small towns you’d never visit otherwise, and they’re often more memorable than anything you’d see at the Met.
I’ve organized these by what type of experience they offer—whether you’re traveling with kids who need to burn energy, looking for contemplative solo wandering, or just want to tell people you spent an afternoon surrounded by 25,000 banana-themed objects.
1. House on the Rock — Spring Green, Wisconsin
Alex Jordan Jr. spent forty years filling his weekend retreat with whatever caught his attention: a three-story carousel that’s never operated, the world’s largest cannon, a room dedicated to miniature circuses, and hallways lined with automated orchestras. There’s no curatorial logic. It’s maximalism as art form.
The appeal isn’t individual objects—it’s the scale of one person’s refusal to stop collecting. You’ll spend three to four hours walking through rooms that have no business existing, and you’ll leave wondering if you imagined half of it.
Admission: $17–$33 depending on which sections you tour. Best for: Families with older kids (elementary age and up), photographers, anyone who loves deeply strange spaces. The walking routes involve stairs and narrow passages; call ahead for accessibility accommodations. Spring through fall offer the best experience—winter hours are limited.
2. Museum of Bad Art — Somerville, Massachusetts
The Museum of Bad Art (MOBA) celebrates work that’s “too bad to be ignored.” It started when antiques dealer Scott Wilson found a painting of an elderly woman in a field and thought: Someone worked hard on this. He and friends began collecting earnest failures—portraits with wonky proportions, landscapes with impossible perspective, still lifes that make you squint.
Every piece was made sincerely to create something beautiful, which makes the collection oddly moving. MOBA rotates exhibitions at the Somerville Theatre basement. It’s free, which feels right for a museum that honors effort over outcome.
Admission: Free. Best for: Art history nerds with a sense of humor, quick visits (30–45 minutes), anyone who’s ever tried to make art and failed beautifully. Wheelchair accessible. Works year-round as an add-on to a Boston-area trip.
3. National Mustard Museum — Middleton, Wisconsin
Barry Levenson, a former assistant attorney general, founded this museum after a late-night grocery store trip following the Red Sox’s World Series loss. He stared at mustard jars and thought: Someone should preserve this. Now the museum holds over 6,000 mustards from all fifty states and seventy countries.
You can sample dozens of varieties, from Wisconsin beer mustard to ghost pepper blends. Levenson gives tours himself when he’s around, and his enthusiasm is contagious. Admission is free; they make money selling mustard, which you’ll want to buy after tasting it.
Admission: Free. Best for: Food-curious travelers, families (kid-friendly and interactive), people who want to taste their way through a museum. Plan 45 minutes to an hour. Fully wheelchair accessible. Open year-round.
4. Museum of Jurassic Technology — Los Angeles, California
Founded by David Wilson in 1988, this museum presents exhibits that blur truth and fiction seamlessly. There are displays about obscure scientific theories, miniature sculptures inside the eye of a needle, and a collection of decaying dice. Is it satire? Serious scholarship? Performance art? Wilson won a MacArthur Genius Grant for this work, so it’s something.
The dim lighting and hushed atmosphere make it feel like a library for things that don’t exist yet. Go in the afternoon when Los Angeles light filters through the windows, and plan to feel confused in the best way.
Admission: $8–$10 suggested donation. Best for: Solo contemplative visitors, artists, people who like puzzles they can’t quite solve. Not ideal for young kids. Plan 60–90 minutes. Limited wheelchair access due to historic building layout—call ahead. Open Thursday through Sunday.
5. Mütter Museum — Philadelphia, Pennsylvania
The Mütter Museum holds over 25,000 specimens: skulls showing disease progression, preserved organs in jars, the conjoined liver of Chang and Eng Bunker (the original “Siamese twins”), and objects surgically removed from patients. It was founded in 1858 to teach medical students about anatomy and pathology.
Content warning: This museum displays real human remains, preserved organs, medical specimens, and graphic medical imagery. Not recommended for children under 12, those with sensitivity to medical content, or anyone uncomfortable with human tissue displays.
If you can handle it, the museum is a startlingly honest look at human fragility and the history of medicine. The wall of skulls alone—each labeled with the cause of death—tells more about 19th-century life than most history books.
Admission: $20–$25; timed-entry tickets required—book several days ahead. Best for: Medical students, medical history enthusiasts, visitors with strong stomachs. Plan 90 minutes to two hours. First floor is wheelchair accessible; call about accessing upper galleries. Open daily; winter weekdays are least crowded.
6. American Visionary Art Museum — Baltimore, Maryland
This museum celebrates work created by self-taught artists, often driven by intense personal visions: sculptures made from toothpicks, quilts with apocalyptic themes, paintings by artists with no formal training but desperate to create. Founder Rebecca Hoffberger opened it in 1995 to give space to work traditional institutions ignore, and Atlas Obscura regularly features it among America’s most distinctive museums.
The building itself is worth seeing—its exterior features a mosaic whirligig by farmer-artist Vollis Simpson. Exhibits rotate annually around themes like “What Makes Us Smile.” It’s joyful and strange in equal measure.
Admission: $16–$20. Best for: Art lovers tired of traditional galleries, families with curious teens, people who want hopeful weirdness instead of dark weirdness. Plan two hours. Wheelchair accessible. Open year-round; visit in spring to enjoy the outdoor sculpture garden.
7. City Museum — St. Louis, Missouri
Sculptor Bob Cassilly turned an old shoe factory into a ten-story playground-museum hybrid. It’s repurposed industrial material: old bridges turned into climbing structures, a school bus hanging off the roof, caves made from spiral staircases. It’s part jungle gym, part art installation, and entirely disorienting.
You’ll climb through tight spaces, slide down ten-story drops, and navigate tunnels where adults have to crouch. Wear closed-toe shoes—they won’t let you in the climbing areas otherwise. Kids love it, but adults have just as much fun once they stop worrying about looking undignified.
Admission: $16–$18. Best for: Families with kids age 3 and up, active adults, photographers (the industrial aesthetic is incredible). Plan three to four hours—you’ll want the stamina. Some areas have wheelchair access; many climbing zones do not. Open year-round; go on weekdays to avoid crowds. Bring a change of clothes; you will get dusty.
8. Barney Smith’s Toilet Seat Art Museum — Alamo Heights, Texas
Barney Smith, a retired plumber, spent fifty years decorating over 1,400 toilet seats: one for the moon landing, another featuring coins from around the world, several dedicated to Texas history. Each is a miniature collage that required real craftsmanship.
The collection now resides at a permanent location after Smith’s passing. Admission is free. You’ll laugh, take photos, and leave with a story about the time you visited a museum dedicated entirely to decorated toilet seats.
Admission: Free (donations accepted). Best for: Road-trippers looking for quirky photo ops, families (totally kid-appropriate despite the subject matter), anyone who appreciates folk art. Plan 30–45 minutes. Wheelchair accessible. Open Friday through Sunday; confirm hours before visiting.
9. International Banana Museum — Mecca, California
Fred Garbutt started collecting banana-related items in 1972 and didn’t stop until he’d amassed over 25,000 pieces: banana lamps, banana phones, petrified bananas, banana art. The museum is aggressively yellow, with no pretense of curation—just wall-to-wall bananas.
It’s exactly what it sounds like. You’ll spend 20 minutes walking through, laughing at the absurdity, buying a banana magnet, and texting photos to friends who won’t believe you.
Admission: Around $3. Best for: Families with young kids, anyone driving through the California desert who needs a break, people who want maximal weirdness for minimal time investment. Wheelchair accessible. Open year-round; summer desert heat is brutal, so plan accordingly.
10. The Museum of Clean — Pocatello, Idaho
Don Aslett, founder of a cleaning company, opened this museum in 2011 to showcase the history of cleaning technology. The collection includes over 6,000 vacuums, washing machines from the 1800s, antique brooms, and vintage cleaning product packaging organized by decade.
What makes it work is Aslett’s genuine enthusiasm for how cleaning went from brutal physical labor to something partially mechanized—which is a bigger story than it sounds. There’s also a section on how marketing shaped our ideas about hygiene, complete with advertisements that range from charming to horrifying.
Admission: $8–$12. Best for: History buffs, people fascinated by everyday technology evolution, families with elementary-age kids who like “how things work” exhibits. Plan 60–90 minutes. Wheelchair accessible. Open Monday through Saturday.
11. Paper House — Rockport, Massachusetts
Elis Stenman, a mechanical engineer, built this house in 1922 entirely from newspaper. The walls, furniture, curtains, and desk are made from rolled and glued papers. You can still read the headlines from the 1920s and 1930s if you look closely—Lindbergh’s flight, Prohibition news, long-forgotten local scandals. It was a twenty-year project, and he lived in it afterward.
The craftsmanship is remarkable—the newspapers are varnished and surprisingly durable. Guided tours explain how Stenman engineered the structure to support weight and insulate against New England weather. It sounds fragile; it’s been standing for over a century.
Admission: $3–$5. Best for: Architecture nerds, families, anyone visiting Rockport or Cape Ann. Plan 30 minutes for the guided tour. Limited wheelchair access due to historic structure. Open seasonally April through October.
Planning your visit
The museums above split into three rough categories: interactive and physical (City Museum, House on the Rock), contemplative and solo-friendly (Museum of Jurassic Technology, Mütter Museum, American Visionary Art Museum), and quick quirky stops (Banana Museum, Toilet Seat Art Museum, Paper House). If you’re traveling with kids under 10, stick to City Museum, National Mustard Museum, or the Banana Museum. If you want something that’ll occupy you for half a day, plan for House on the Rock or City Museum.
Most of these museums are in small towns, which means you’ll need to build the trip around them rather than adding them to an existing itinerary. That’s a feature, not a bug—you’ll end up seeing parts of America you’d never visit otherwise. Spring Green, Wisconsin (population 1,600) has exactly one attraction, and it’s a sprawling monument to one man’s refusal to stop collecting things. That’s worth the drive.
TripAdvisor and Travel + Leisure occasionally feature these museums in “offbeat America” roundups, but most don’t chase press coverage. They exist because someone cared, and they survive because enough visitors show up and pay admission. Check museum websites before you go—small institutions sometimes close unexpectedly for maintenance, weather, or simply because the owner needed a day off.
Frequently asked questions
How much should I budget for admission? Most charge $3–$20, with several completely free. Factor in extra for gift shop purchases—you’ll want the souvenir banana phone or a jar of ghost pepper mustard.
Which museums are accessible for wheelchair users? National Mustard Museum, Museum of Bad Art, City Museum (ground floor), Banana Museum, Museum of Clean, and Toilet Seat Art Museum offer full or substantial wheelchair access. Mütter Museum, American Visionary Art Museum, and House on the Rock have partial access; call ahead. Museum of Jurassic Technology and Paper House have limited access due to historic building constraints.
Can I visit multiple museums in one trip? Wisconsin has two on this list (House on the Rock and National Mustard Museum), about 90 minutes apart. Otherwise, these are scattered—which is half the point. Pick one, build a weekend around it, and enjoy the small town it’s in.
Are these museums legitimate or just tourist traps? Both, depending on your definition. They’re genuinely run by people who care deeply about their collections. They’re also profoundly weird. The Museum of Jurassic Technology won a MacArthur Grant; the Banana Museum is wall-to-wall kitsch. You’ll get what you came for.
The best small museums in the USA reward the detour. Pick the one that sounds most absurd, find out what small town it’s in, and go. You’ll leave with better stories than anything the usual tourist circuit offers—and you’ll understand a little more about the specific, obsessive ways people decide to spend their time on earth.
