The Navarre-Anderson Trading Post survives from the territorial period. The simple one-and-a-half-story log structure utilizes the traditional French construction technique of pièce-sur-pièce. Hewn timber is mortised, tenoned, and pegged to form a sturdy framework. The door has a simple but delightful Greek Revival surround. The building is associated with two early Monroe settlers and traders—French Canadian François-Marie Navarre (known as Heutreau, 1759–1836) and Scottish-born John Anderson. It has been moved and restored several times; today it stands on the River Raisin, in an outdoor park where the Monroe County Historical Museum interprets it as the single dwelling of a fur trader in 1799. Next door is a kitchen building; at the corner is a country store.
