Merchant's House Museum
The Merchant's House is a row house built in 1831 - 1832 by developer Joseph Brewster and purchased by merchant Seabury Treadwell in 1835. Treadwell's last daughter, Gertrude, lived in the house until 1933, leaving it largely unchanged and unmodernized so that it became a time capsule of upper class life in ninteenth-century New York. The parlors are fine examples of Greek Revival architecture.
The house was converted to a museum in 1935, featuring exhibits on New York's transition from farming community to an industrial and mercantile colossus. The facility underwent restoration in 1979 and when I visited in the Fall of 2007, it was undergoing another set of renovations, which accounts for the presence of construction equipment in the photos.
