Investigators are working to learn what caused a fire that destroyed an iconic Buckhead sports bar.

Atlanta Fire says it was one of their crews who first spotted the blaze around 8:11 a.m. Monday in the 3200 block of Roswell Road NE.

Crews from Atlanta Fire, DeKalb Fire, Cobb Fire, and City of South Fulton Fire departments worked through the morning to get the fire under control. Firefighters started battling the blaze from the interior of the building, but conditions became unsafe. Crews went on the defensive, retreating to the exterior to battle the fire.

The roof of the iconic Buckhead bar collapsed, making it more challenging for firefighters to get to pockets where the fire is still burning.

As of Monday afternoon, crews were still outside the structure working to put out hot spots. 

SKYFOX 5 flew overhead where a large amount of smoke could be seen coming from the building. Smoke could be seen for miles.

Roswell Road in Buckhead has been closed as firefighters battle the large blaze.
