Huge flames lit up the night sky. Firefighters also had to deal with a lot of smoke at the scene.
The fire was out before sunrise Tuesday, and no one was injured.
A building collapsed during another intense fire, this one in the Southwest Side Brighton Park neighborhood.
The fire happened in a two-story vacant building in the 4600-block of S. Troy.
No injuries were reported, but firefighters were unable to search the building as a result of the collapse.
There was no word early Tuesday on what caused either fire.
