HARPERS FERRY, W.Va. — Investigators are working to determine the cause of a massive three-alarm fire that ripped through buildings Thursday morning in the historic community of Harpers Ferry.

“We had flashing lights outside the window, and I woke up and came out and saw flames” said neighbor Chris Corder.

“We always worry about fires in this town because everything is so tight-knit.”

The first 911 call came in around 3:15 a.m., drawing about 80 firefighters from Jefferson and Berkeley counties in West Virginia, Loudoun County, Virginia and Washington and Frederick counties in Maryland to the scene.

The fire destroyed three buildings and a shed near the historic district.

There were several businesses inside each building, including the popular Private Quinn’s Pub, as well as two apartments. They are all a total loss. No damage estimate has been released.

No one was injured.

“It will have an impact on these independent businesses and the few people that live in this immediate area,” said David Fox with the National Park Service.

“It will be devastating to them.”

Because of the proximity to the MARC station, MARC on Thursday morning initially advised commuters to use the Duffield or Brunswick stations. It then tweeted that Train 878, the last train to depart Harpers Ferry, would board from the opposite track at the station.

Area resident David Holmes, a firefighter, posted photos of the fire on his Facebook page.
