CONNEAUT LAKE, Pa. — Fire today destroyed a restaurant and beach club at a 121-year-old amusement park in northwestern Pennsylvania.

The ruins at Conneaut Lake Park, north of Butler, could smolder for a week, Summit fire Chief Gig King said.

The complex that burned contained the Beach Club and Downunder Beach Bar, as well as the Dockside banquet facility.

“When it went up, it went up pretty quickly,” King said.

The Beach Club was built in 1936, and the neighboring banquet pavilion recently had been renovated as part of efforts to revitalize the seasonal park, which didn’t open during the summers of 2007 and 2008 because of long-standing financial problems.

The park is now run by a public nonprofit, the Trustees of Conneaut Lake Park Inc., though the entertainment complex is leased by three people doing business as Park Restoration LLC. One of those partners, Joyce Popovich, said weddings and other events had been booked at the banquet facility into next year.

“We will do whatever we have to do to make it work,” Popovich said of those events.

The park is home to the Blue Streak, one of the oldest wooden roller coasters in America.

The fire was reported shortly before 2:30 a.m. by a boater. At least nine fire companies responded.

A damage estimate for Thursday’s fire wasn’t immediately available.
