Boonville was a busy steamboat town in the mid-1800s, and one short stretch of original cobblestone — laid to give wagons traction on the steep pull up from the riverboat landings — survives just north of Main Street. It runs only about a block and a half but is one of the best-preserved examples of its kind on the Missouri.
Stand at the top and you can see how the slope down to the river dictated the town's layout: the wagons loaded grain and hides at the landings below, the warehouses lined the bluff, and the brick commercial buildings climbed up Main Street behind. The street is on the National Register and still drivable, though most visitors just walk it.
