The Statue of Liberty went dark around 10 p.m. Tuesday as the lights on the structure suddenly shut off, leaving a dramatically vacant New York Harbor in its wake.

An EarthCam livestream showed Lady Liberty almost completely engulfed in darkness, with the exceptions of her torch and crown, which remained illuminated.

A National Parks Service spokesperson said the blackout was a technical glitch.

“We believe it is related to the activation of a new emergency backup generator which is being installed as a part of our last remaining Hurricane Sandy recovery project,” the spokesperson said.

The lights went back on sometime after 11:30 p.m.

Some lights on the Statue were temporarily off tonight. Likely related to new emergency generator/Hurricane Sandy recovery project work.
