Astor Row is a landmarked block of 28 three-story brick rowhouses on the south side of West 130th Street in Harlem, built between 1880 and 1883 on land originally owned by John Jacob Astor and developed by his grandson William Backhouse Astor Jr. Unusual among Manhattan rowhouses for their front yards, side yards, and wooden front porches, they were designated New York City Landmarks in 1981 and underwent significant restoration in the 1990s, and remain among the most architecturally distinctive survivals in upper Manhattan.
