Built 1827 — a museum from 2004
The house as museum: The house Jean Baptiste de Richardville built in 1827 at 5705 Bluffton Road — subsidized by the United States under the 1826 Treaty of Mississinewa, and described by the History Center as the oldest Native American building in the Midwest and the only surviving treaty house in the nation — passed to the Allen County–Fort Wayne Historical Society in 1991. The society restored the exterior, and on Saturday, 26 June 2004, the house opened for public tours. Since 2007 its Miami Indian Heritage Days series has presented Miami history, culture, and art at the house on the first Saturday of the month, May through November. On 2 March 2012 the house was designated a National Historic Landmark — only the second in Allen County. (The house's building history is in the Architecture record; what Richardville's fortune built is in the Wealth record; this entry is its museum life, which is the History Center's.)
