01 / District boundary stone
On the east face of a pillar set at a district border,it reads "From here east, Mikasa District; west, Naka District."

A relic of the old Hita Kaido road (日田街道), this 117 cm square stone pillar marked the border between Mikasa District and Naka District. Erected in 1817 (Bunka 14), five years after Ino Tadataka surveyed this area, it was badly weathered and moved to the city museum in 2000 (Heisei 12). A marker stone and explanatory board now stand at the original site.
