Built in 1832, the Merchant’s House has survived virtually intact with the furnishings of the merchant family that lived here almost 100 years. It is one of only 2,500 National Historic Landmarks and has Landmark status in New York City for both its late-Federal brick exterior and its elegant Greek Revival interiors. It is also listed on the National Register of Historic Places. The Museum educates the public about life in the mid-19th-century during the significant period when New York established itself as the center of U.S. commerce and became a "world city" on par with London and Paris. It achieves this by displaying and interpreting the possessions of the Seabury Tredwell family, providing visitors an authentic and intimate look at domestic life in the 1860s. The Museum is an invaluable resource for scholars; hosts frequent public programs for adults; and brings in elementary and secondary school children for lessons on 19th-century New York and historic preservation.
