The 32-foot tree, given every year since 1996 in gratitude for US assistance in World War II, is hung with 700 images of Edvard Munch's iconic painting.
“In a way, it symbolizes all the angst in preparing for an excellent Christmas,” Ambassador Kare Aas told Washington Post before coming to the lighting ceremony on Tuesday night. “I, myself, have that feeling. I’m not the only one who wants to scream from time to time.”
The unusual adornment was part of the celebrations for the 150th anniversary of Munch's birth. The tree was lit by Lt. Gen. Christopher Bogdan of the US Air Force.
The Norwegian embassy also arranged for Santa Claus to be present, with gifts for children, and provided mulled wine and ginger biscuits.
