A two-alarm fire damaged an office building in Govans last night but did not injure anyone, fire officials said.

The fire began about 10:15 p.m. in the York-Belvedere Medical Center in the 5800 block of York Road, said Fire Department spokesman Chief Kevin Cartwright. The fire damaged much of the second floor and part of the third. A crack appeared in the exterior of the stone building, which prompted firefighters to evacuate, Cartwright said. No one appeared to be in the building when the fire erupted, Cartwright said. The cause of the fire was not known last night.
