The Seabury Tredwell House was built in 1832 and occupied by the Tredwells, a merchant family from 1835 to 1933. Today, it is designated as a National Historic Landmark and is the only home in New York City to have survived intact, both inside and out, from the 19th century. The Greek Revival period rooms of the Merchant’s House show the lifestyle of this wealthy merchant family and their Irish servants. The collection includes over 3,000 items that were the possessions of the Tredwells, among them furniture, household items, decorative arts, and clothing. The 19th-century garden also is open to visitors.
