The side of a century-old building in historic downtown Manassas collapsed over the weekend, likely a result of high winds that swept through the region.
The collapse occurred Saturday at about 9 p.m. at 9414 Battle St.
City spokeswoman Patty Prince said no one was injured, but 14 people were evacuated from nearby apartments as a precaution.
The building was vacant and had most recently housed a dry-cleaning business.
Property records show the building dated back to 1906.
Prince said investigators are continuing their work, but currently believe high winds associated with Sunday's winter weather were to blame.
Prince said Monday that crews were preparing to take down the entire building.
