The fire that started yesterday at the Serbian Orthodox Cathedral of St Sava in Manhattan sent plumes of smoke billowing into the city's skyline.
The fire was largely extinguished three hours later, but firefighters had to beat back small pockets of flames.
Authorities didn't disclose the cause of the fire, which destroyed the church's roof.
Fire officials said the church's caretaker ran inside the Gothic Revival style building to try to put out the blaze but suffered minor smoke inhalation and had to be rescued.

"I was just inside that building three hours ago," a heartbroken Dex Pipovic, told PIX11 News. He said he had been going to the church for seven years.
Alex Velic, 31, the caretaker's stepson, told the Daily News he lives next door. He said he smelled smoke and came outside and saw the church on fire.
"Once the fire caught the wood there was flames coming out of the top of the church. That's when people were going crazy," Velic said. "I'm in shock. I don't know what to say. It's sad."
City Council Member Corey Johnson called for a full investigation into the cause of the fire.
"This is a huge loss for the community," he said. "In addition to being a place of worship, this historic building was a New York City landmark, treasured by the people" living in the neighborhood.
The church was designed by architect Richard M. Upjohn and was built in the early 1850s. One of its earlier congregants was novelist Edith Wharton, who wrote "The Age of Innocence." She was married in the church in 1885.
