Astor Place is a short, two-block street in NoHo/East Village, in the lower part of the New York City borough of Manhattan.  It runs from Broadway in the west, just below East 8th Street; through Lafayette Street, past Cooper Square and Fourth Avenue; and ends at Third Avenue, continuing as St. Mark's Place.  It borders two plazas at the intersection with Cooper Square, Lafayette Street, Fourth Avenue, and Eighth Street – Alamo Plaza and Astor Place Station Plaza.  "Astor Place" is also sometimes used for the neighborhood around the street.  It was named for John Jacob Astor (at one time the richest person in the United States), soon after his death in 1848.

Colonnade Row, also known as LaGrange Terrace, on present-day Lafayette Street in New York City's NoHo neighborhood, is a landmarked series of Greek revival buildings originally built in the early 1830s.  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 buildings are listed on the National Register of Historic Places under the name LaGrange Terrace and the facades remain standing on Lafayette Street south of Astor Place.

The John Jacob Astor Hotel, originally known as the Hotel Astoria, is a historic former hotel building located in Astoria, Oregon, United States, and listed on the National Register of Historic Places (NRHP).  It is one of the tallest buildings on the Oregon Coast and is a "prominent landmark" in Astoria.  Constructed in 1922–23, the hotel opened in 1924 and initially was the city's social and business hub, but soon was beset with a variety of problems, and struggled financially for years.  It was renamed the John Jacob Astor Hotel in 1951, but a decline in business continued, as did other problems.  The building was condemned by the city for safety violations in 1968 and sat vacant for several years until 1984, when work to renovate it and convert it for apartments began.  It reopened as an apartment building in 1986, with the lowermost two floors reserved for commercial use.  The building was listed on the NRHP in 1979.
