Long-Banta Home
​1865

One of the best examples of Victorian architecture in the area. This house was owned by three successive generations of the James Long family before its donation to the Historical Society. It served as the home of Parke M. Banta, US Representative and the first General Counsel for the Department of Health Education and Welfare during the Eisenhower Administration. The Long-Banta home is regularly visited by the Paranormal Task Force seeking if any spirits, ghosts, hauntings, etc are present. 

Old Presbyterian Church Museum
1832-33

​This is the oldest surviving Presbyterian Church building west of the Mississippi River. The building served as a house of worship until 1907 when the new church was built one block East on Breton Street. This building has had many uses after the congregation moved. It was used as a Silent Movie theatre, the Boy Scout Meeting Hall, a gymnasium for basketball, the temporary County Library, and the first Christian Bookstore. It was first converted to use as a museum during the Potosi Bicentennial in 1963. The building still serves as one of the Historical Society museums.
Next to the church, in the Old City Cemetery, is the tomb of Moses Austin and his wife Maria Browne Austin.
