Museum

The Nauvoo State Park Museum is a house built by Mormons in the 1840s, remodeled by Icarians, and later owned by the Rheinberger family from 1850 to 1948. It has been staffed as a museum by the Nauvoo Historical Society since 1954. The restored home features a stone-arched wine cellar and a press room, and is the only Nauvoo wine cellar open to the public. This also is the location of Nauvoo's first vineyard, a 3-acre concord grape vineyard planted in 1851 which has been producing grapes since the mid-1800s. The museum itself exhibits artifacts from all periods of Nauvoo's history, including Native American, German, Mormon, Icarian, Civil War, and other artifacts.
