UPPER EAST SIDE - A massive blaze tore through the prestigious Regis High School on the Upper East Side Friday night, fire officials said.
The inferno forced school officials to cancel classes on Monday and all activities and evening events "until further notice," according to a note on its web site."
"There was a bad fire at Regis," read a note on the site from the school's president, Philip Judge.
"The damage was significant, but remarkably limited."
The two-alarm fire broke out on the second floor of the Catholic school, on E. 84th Street, near Park Avenue, around 11:50 p.m.
It took more than 100 firefighters from 25 units about 90 minutes to bring the inferno under control, according to the FDNY.
"The upper gym and faculty lounger are unusable, but the damage is largely contained there," read the note from Judge, who added that there was water damage to the auditorium and physical education office.
"Please say a prayer of thanksgiving that no one was hurt, and one of gratitude for the firefighters who worked so ahard to contain and put out the fire."
Two firefighters were taken to New York hospital with minor injuries, but no one was believed to be inside at the time flames erupted.
Fire officials said the blaze did not appear to be suspicious, although the cause was under investigation.
A call to the school, which offfers a free Jesuit education to high-performing students, was not returned.
Among the cancelled activities was an end-of-the-year dance that was scheduled for Saturday night.
"It's terrible," said George Batista, a doorman at a building across the street from the school.
"It's very depressing, especially for the kids who have their celebration - they can't have this celebration because of this terrible fire."
Also cancelled Saturday was a robotics event.
Judge said that he expects classes to resume Tuesday.
