Really beautiful image, Gus! And brave of you to stay in the park after dark! I live in the building at the left of the image so I know exactly where you were standing when you took this! :)
Harold, the building with the double towers is an apartment building called the San Remo, very popular with the celebrities (the co-op board denied approval to Madonna, however ;)). The lower one to the left is the Dakota where John Lennon lived and Yoko still owns a couple of apartments there. Parts of the movie, Rosemary's Baby, were also filmed there.
