Nearly all of SoHo falls within the SoHo Cast Iron Historic District, which became a National Historic Landmark in 1978, five years after being deemed a landmark by the city. This designation encompasses more than 200 buildings constructed in the latter half of the 19th century of cast iron, an innovation that presaged the use of steel and the construction of skyscrapers while allowing for the same elegance as carved stone. Because of this, nearly every block of SoHo offers plenty of impressive architecture and a sense of history.
