The Duluth Fire Department has ruled the cause of an abandoned church fire from this summer as undetermined.
Firefighters responded to the fire in Duluth's East Hillside in mid August.
The building was a former church, located at 901 East 3rd Street.
Those with the fire department say the church had been abandoned for at least a few years.
When crews arrived on scene they found the fire on the second floor spreading up the steeple.
No one was inside the building at the time of the fire, and no injuries were reported.
