Fort Defiance was one of the last garrisoned stockade forts constructed in territorial Wisconsin. In the booming lead mining region, an area of early settlement, local settlers built the fort in 1832 when developing tensions over Indian rights erupted in the Black Hawk War. Although Fort Defiance did not undergo attack, it had a garrison of about forty militia men who were said to be among the best drilled in the territory. The fort stood on a hill about 300 yards east of here and was enclosed by a sharply pointed palisade of heavy timbers set face to face, creating an almost impenetrable wall except for the musket loop holes. Measuring 80 feet wide by 120 feet long and 18 feet high, Fort Defiance had two blockhouses located at opposite corners of the stockade. Within the walls were two buildings used to accommodate the garrison and the families of settlers in case of siege. There are no visible remains left of Fort Defiance.
