This is a movie showing the NYC skyline from around Fulton St. down to Battery Park filmed on May 10, 1903.
Those of us either living in or visiting the NYC area won't see most of these buildings anymore. Now you see their piers sticking up out of the water, like toothpicks on a tray of canapés.
The person with this YouTube channel has enhanced the image quality and added audio ambiance.
A LOT more sky back then ...
