This is an apartment building called The Dakota. It stands on NYC's Upper West Side and was used as The Bramford apartment building for Rosemary's Baby. The building itself does have a dark past, but it doesn't have much to do with Satanic cults. Now, it's best known as the site of John Lennon's fatal gunshot wound.
While we can't speak to children of the devil or occult rituals, there's a different aspect of the building that's a bit supernatural. Before his death, John Lennon claimed to have seen a crying ghost lady roaming the halls. And after, Yoko Ono has claimed to see Lennon's ghost.
