Fire heavily damaged a 140-year-old California church building in Forestville, California.

A spokesperson for Forestville No. 3 Fire District said the fire was prevented from spreading from the building owned by the Forestville Church of Christ.

The Press Democrat reports the church was built in 1879 with old-growth redwood and was a, “piece of local history as well as a religious gathering place.”

The cause of the fire remains unknown.  The Federal Bureau of Alcohol, Tobacco, Firearms and Explosives are assisting in the investigation.
