This park preserves the site of historic Davidsonville in Randolph County. Established in 1815, the town included the Arkansas Territory's first post office, courthouse, and land office. Bypassed by the Southwest Trail, an overland route from St. Louis to the border of Mexico, the town faded by the 1830s. Archeological excavations here are uncovering remarkable finds of streets, foundations, and objects that tell a fascinating story of life on the Arkansas frontier following the Louisiana Purchase. Park exhibits and interpretive tours provide information about this important frontier town. Visitors can take a tour and learn all about Arkansas frontier history.
