Someone broke in the early morning hours and took a safe out of the building that contained $8,000, but officials say most of their money had been deposited in the bank just before the burglary.
Even so it was a blow.
"For a place like this it's like robbing from the church. There's a lot of people that work long hours to renovate this building, they put their heart and soul into it and for somebody to take from you is kind of a kick in the teeth," Bob McNamara said.
The festival continued as planned Sunday.
It featured Irish and American music and dance, as well as exhibits and family activities.
