Fort Abraham Lincoln State Park

"Touring Fort Abe Lincoln (10 miles southwest of Bismarck) feels a little like time-traveling back to your last elementary field trip—in part because, on many weekdays, you'll see busloads of schoolkids wandering the grounds. But the history preserved here is compelling, no matter what your age. Highlights include interpreters in Civil War-style uniforms, rows and rows of beds in the barracks, a re-created Native American village, and George Custer's actual "Mansion on the Prairie." A great museum ties all the historical pieces together."
