A 2-alarm fire ripped through part of the Calvary Cathedral in Fort Worth early Thursday.
The fire was contained to the second floor of the office building, sparing the sanctuary and school. The fire destroyed several offices that the church said are vital to daily operations.
At about 3 a.m., drivers on Interstate 35 North were the first to report the flames. Security guards were patrolling the campus when the fire started, but they didn't notice the fire until flames began shooting out of the roof.
It took firefighters about an hour to get the fire under control. Officials with the Fort Worth Fire Department said there is heavy smoke, fire and water damage throughout the first and second floors.
Investigators believe the fire started on the second floor in a study or library area. The exact cause of the fire is under investigation.
The school was not affected at all by the fire and classes are being held at their normal times.
