A fire early Friday heavily damaged the University of Connecticut's oldest building, a colonial-style house built in 1769 that is part of the school's historic district. No injuries were reported.

Firefighters were called to the Whitney House at about 6 a.m. and the building was almost fully engulfed in flames at one point, UConn officials said. The fire was deemed under control about an hour later, but firefighters remained at the scene to put out hot spots.

The Whitney House, which was not currently in use, is one of several private residences in Storrs that predate the founding of the school and were acquired by the university, whose historic district is on the National Register of Historic Places.
