Investigators say the fire that damaged the historic Orpheum Theatre in Madison was intentionally set.
Fire Department Lieutenant Bradley Olson says investigators have been looking at burn patterns and debris.
Theater co-owner Eric Fleming says he's not surprised it's arson because it's the third fire at the 76-year-old State Street landmark in less than a year.
The December 19th fire was discovered by an employee arriving for work.
Damage is estimated at 100-thousand dollars. Managers hope to reopen the theater and restaurant later this month.
