Historic Thiensville
Although not incorporated until 1910, the Village of Thiensville became a settlement in 1842 when John Henry Thien constructed a grist mill. A German “Free Thinker,” Thien disavowed organized religion and banned churches here, attracting other Free Thinkers to the settlement. By the 1880’s, the village became a thriving commercial center with mills, stores, hotels, blacksmiths and wagonmakers
