PopSpots is a website about those places, primarily in New York City, where interesting events in the history of Pop Culture took place; like album cover shots, places where movies and tv shows were filmed, and sites on which paintings were based.
Some of the places I tracked down myself for fun. Others are places I've read about and gone to take a look.
Manhattan is constantly being torn down and rebuilt anew, and I'm trying to find these places while they are still around.
