Since 1965, The Garnavillo Historical Society, a non-profit organization, has researched, recorded and preserved the history of Garnavillo and the surrounding area. The Historical Society's museum complex includes 3 buildings. The museum at 203 N Washington Street, which was built in 1867 as a Congregational Church, contains archives and exhibits with early manuscripts and books dating back to the 18th century, old maps, photos, Indian artifacts, period furniture, pioneer and civil war items, a 1903 Crestmobile, Busy Bee vacuum and much more. An original 1830's log cabin from the area was dismantled, moved and reconstructed in the City Park. The third building is the I.O.O.F & Masonic Lodge Hall built in 1860 at 105 W Centre Street. All buildings are within easy walking distance of each other. The Society also owns a fourth building, the 1860 Law Office of Crosby & Brown on Main Street Garnavillo, which is currently a private law office. The museum complex is hosted by volunteers and open to the public weekends during the summer season and by appointment at all other times. Admission is free, but donations are needed and appreciated.
