Mayor Bill de Blasio flipped the switch Wednesday night to light the Rockefeller Center Christmas Tree following a televised extravaganza that featured performances by Diana Ross and Tony Bennett.
Police officers were plentiful, and spectators were funneled through security.
The 75-year-old tree was donated by a couple in Wallkill, 60 miles (100 kilometers) north of the city.
It will remain on display until Jan. 7. Then it will be given to Habitat for Humanity to help build homes.
