Alabama fire marshals are surveying the damage from a fire at Choctaw County High School in Butler.
The school was badly damaged in the fire reported about 7:45 p.m. Tuesday.
The fire appeared to heavily damage the west wing, which consists of mostly classrooms, the science lab and computer room.
The fire was contained at about 2 a.m. Wednesday, but small flames were still visible at that time. Fire breaks prevented the blaze from spreading further. Some of the walls in the building had started to lean.
The Alabama State Fire Marshal's Office began surveying the scene after the heat of the fire subsided about 9 a.m. Wednesday. The cause was not immediately known.
Classes were suspended Wednesday for the high school but school was held as normal at other district campuses.
Choctaw County High School was built in 2005.
