Colonnade Row, also known as LaGrange Terrace, is a group of 1830s row houses on present-day Lafayette Street in the NoHo neighborhood of Manhattan in New York City. They are believed to have been built by Seth Geer, although the project has been attributed to a number of other architects. The buildings' original name comes from the Marquis de Lafayette's estate in France, but the series of nine row houses, of which four remain, owe their existence to John Jacob Astor, who bought the property and whose grandson John Jacob Astor III later lived at No. 424. The remaining buildings are New York City designated landmarks and listed on the National Register of Historic Places under the name LaGrange Terrace. The facades remain standing on Lafayette Street south of Astor Place.
