Incorporated in 1962, the Keokuk County Historical Society is open Wednesdays and Thursdays, 9 to 4:00 p.m. The Society is a combination of memorabilia and records dating back to the 1800s, including the records of 75 Keokuk County cemeteries. Several photographs, quilts, books, maps, and antiques can be found on display throughout the building.

The Stone House
The oldest house in Sigourney was given to the Society in 1985 by the descendants of the Mohme family. The house was built from 1855-1863 with stone walls 18-inches thick. The Stone House can be seen by appointment.

The Historical Society is located at the corner of Elm and East Streets.

Built in 1887, the ownership of this former St. Paul's United Church of Christ transferred to the Keokuk County Historical Society on December 27, 1972. It was with the understanding that the sanctuary would remain intact and that the building would be maintained as a permanent home for the County Historical Society, its files, and museum.
