The New York City Landmarks Preservation Commission (LPC) is the New York City agency charged with administering the city's Landmarks Preservation Law. The LPC is responsible for protecting New York City's architecturally, historically, and culturally significant buildings and sites by granting them landmark or historic district status, and regulating them after designation. It is the largest municipal preservation agency in the nation. As of July 1, 2020, the LPC has designated more than 37,800 landmark properties in all five boroughs. Most of these are concentrated in historic districts, although there are over a thousand individual landmarks, as well as numerous interior and scenic landmarks.

Pennsylvania Station was a historic railroad station in New York City that was built for, named after, and originally occupied by the Pennsylvania Railroad (PRR). The station occupied an 8-acre (3.2 ha) plot bounded by Seventh and Eighth Avenues and 31st and 33rd Streets in Midtown Manhattan. As the station shared its name with several stations in other cities, it was sometimes called New York Pennsylvania Station. Originally completed in 1910, the aboveground portions of the building were demolished in 1963, and the underground concourses and platforms were heavily renovated to form the current Pennsylvania Station within the same footprint.
