Washington, DC
The oldest structure on its original foundation in D.C. was once mistakenly promoted as a place where George Washington stayed, helping save it from demolition.
Nashville, TN
The castle-like former state prison operated from the nineteenth century into the 1990s and later became a recognizable film location. The complex is restricted and unsafe for casual entry; OddWay should route only to lawful exterior viewpoints and never encourage trespassing.
Tonopah, NV
The 1901–1911 cemetery contains miners, boomtown residents, and victims of the 1911 Belmont Mine fire; its position beside the Clown Motel adds to its eerie reputation.
Tucson, AZ
Originally built as a movie set, Old Tucson accumulated saloons, streets and false-front buildings used in decades of Western productions. The attraction lets visitors walk through a fabricated Old West that became historic in its own right.
Valdez, AK
The original Valdez townsite was abandoned after the 1964 earthquake left the waterfront dangerously unstable. Roads, markers and open ground preserve the location of a community that was physically moved to a safer site several miles away.
Key West, FL
One of Key West's oldest surviving houses, filled with island history and period artifacts.
Elliston, VA
Built in 1878, this metal truss bridge carried traffic until 1971 before being preserved at the northbound Ironto Safety Rest Area on Interstate 81. It has been restored as a pedestrian bridge, turning a highway rest stop into an unexpectedly good piece of surviving nineteenth-century transportation history.
St. Augustine, FL
Living-history store crowded with turn-of-the-century gadgets, patent medicines, and strange household inventions.
St. Augustine, FL
Tiny cedar-and-cypress schoolhouse promoted as one of the country's oldest surviving wooden school buildings.
Elk River, MN
This working historic farm interprets nineteenth-century agriculture on the former property of Grange founder Oliver H. Kelley. Costumed programs, livestock and historic buildings turn agricultural history into a physical landscape rather than a static display.
Olowalu, HI
Hundreds of carved human and geometric figures are associated with the Olowalu petroglyph field. Access conditions and land stewardship have changed over time, so OddWay should route only when a lawful current path is confirmed and should never encourage touching, tracing, or adding marks.
Olustee, FL
Preserved battlefield landscape from Florida's largest Civil War battle.
Mandan, ND
Reconstructed earthlodges stand amid the archaeological remains of a Mandan village occupied for centuries near the Heart and Missouri rivers. The site is within Fort Abraham Lincoln State Park and interprets Indigenous life that predates the military fort by generations.
Wilmington, DE
Wilmington renamed this small park One Love Park in recognition of Bob Marley’s time living and working in Delaware. State historical material notes that Marley lived nearby in the 1960s and worked local industrial jobs while raising money for his music career. His former residence is private and should not be approached as part of the stop.
Oneida, NY
Nearly 300 members of the radical Oneida Community once lived communally in this enormous mansion while practicing group marriage, communal child rearing and religious Perfectionism. The 93,000-square-foot building survives as a museum, inn and residence with daily self-guided museum access and scheduled deeper tours.
Preston, ID
Restored 1890s academy associated with early education in southeast Idaho. Public tours and events vary, so confirm access before routing for the interior.
Sweetwater County, WY
A remote interpretive site marks the Oregon Buttes, a stark Red Desert landmark that helped emigrants navigate after crossing the Continental Divide.
Salem, OR
A memorial garden and columbarium honor thousands of former hospital patients whose cremated remains were stored for decades in copper canisters; visit quietly and respectfully.
Salem, OR
The museum interprets the history of Oregon's state psychiatric hospital through patient stories, medical objects and changing approaches to mental-health treatment.
Guernsey, WY
Repeated wagon traffic physically cut deep grooves into the sandstone, leaving some of the clearest surviving Oregon Trail ruts.
Blakely, GA
A tall wooden flagpole in Blakely's courthouse square was erected in 1861 during the Civil War and has survived into the present landscape. Its endurance makes it an unusual physical relic of the war era rather than a later commemorative monument.
Helena, MT
A preserved Queen Anne mansion used by Montana governors from 1913 to 1959, offering a close look at political and domestic life from the early statehood era.
Baldwin Park, CA
A tiny replica of the chain's first 1948 drive-thru stand reconstructs the kitchen and two-way speaker system that helped define California car culture.
Hastings, NE
A historical marker at the former Perkins Products factory location identifies the place where Kool-Aid production became a Hastings industry. The building/site gives travelers a second, more geographic connection to the drink beyond the museum displays.
