Oneida Community Mansion House collections include a range of primary source materials related to the Oneida Community: family portraits, historical photographs in the thousands, period furniture, braided tapestries, books, Community-designed clothing, and ephemera - more than 30,000 objects in all – which illustrate the intellectual, cultural, and business life of the Community.  

The Mansion House building, a National Historic Landmark, is a valuable resource for studying the architecture of communal living. The existing Mansion House was designed and built in stages between 1861 and 1878. The 1862 house, designed by Community member Erastus Hamilton, included sleeping rooms, a library, sitting rooms, and the central gathering space, the Family Hall. The Tontine (1863-1864) served as the communal dining hall, kitchen, laundry, and workspace. In 1869, the Community added the South Wing, with attics that modeled Second Empire, Mansard style, to the main house to accommodate the communal raising of children. The New House, designed by Lewis W. Leeds, was finished in 1878 to accomodate the Wallingford, Connecticut branch of the Community, which had merged with the Oneida branch. The Lounge, designed by architect Theodore Skinner, was added by Oneida Community Ltd. in 1914.
