A Tribeca Citizen reader submitted this video (via Curbed) of One World Trade Center on a windy day last week. As you can hear, when the wind blows, the tower emits a spooky, high-pitched wailing sound. This isn’t the first time such a sound has been reported.

“I live a couple of blocks from the tower, and first heard this very eerie sound during Hurricane Sandy last year,” writes Kenny Cummings. “I’ve heard it only once afterwards, sometime last winter. I assumed once the building’s framework and windows went in, the airflow would be redirected. At 3:15 a.m. Wednesday morning, I awoke to the sound. It was slightly different in timbre, with two tones this time. I couldn’t be sure what it was at first, but after a moment I realized it was the Trade Center…I’m sure all of downtown hears this—it’s unmistakable and very chilling.”

I can imagine it’s pretty unnerving. But hey, at least you’re not on Staten Island.
