Arrow Rock stands as a pioneer town tied to the Boon's Lick Country and the expanding frontier. In the twenty-four-acre park are Arrow Rock Tavern, built by Joseph Huston about 1834 for travelers on the Santa Fe Trail and later restored and operated as a museum and inn by the State Society of D.A.R. and the State of Missouri; Arrow Rock Academy museum, a former girls' school chartered in 1845; a one-man jail; the state-restored George C. Bingham House; and other sites. Southwest of town are Sappington and Arrow Rock cemeteries, the Sappington and Marmaduke houses, Nathaniel B. Tucker's home Ardmore, and the site of Thomas A. Smith's prairie farm Experiment. About twelve miles southeast is the grave of fur trader William H. Ashley, Missouri's first lieutenant governor. Across the river is Boon's Lick, where Daniel Boone's sons probably boiled salt as early as 1807. Near town lived Doctor John Sappington, noted for his Anti-Fever (quinine) Pills, author of the first medical book west of the Mississippi, and founder of the Sappington School Fund, as well as Governors M.M. Marmaduke, John S. Marmaduke, and C.F. Jackson. The site was noted by explorers and travelers: the Frenchman D'anville marked Pierre a Fleche on his 1755 map of the Missouri River, the Lewis and Clark Expedition noted it in 1804, and S.H. Long of the Yellowstone Expedition said in 1819 that it was named for Indians who used outcropping flint to point their arrows. George C. Sibley, trading agent from Fort Osage, built and operated a blockhouse here as an Indian trading post in 1813-1814, and the area also included Cox's Fort, McMahan's Fort, and Cooper's Fort across the river, family defenses in the War of 1812. In 1821 William Bucknell crossed the river here at what became Santa Fe Crossing on the first successful trading expedition to Santa Fe. The town was laid out as New Philadelphia in 1829, later renamed Arrow Rock, served as the seat of Saline County for one year in 1839, and had part of the town burned during the Civil War.
