A long-closed administration building at troubled Knoxville College, a historically black institution, was destroyed in a fire Monday night, officials said.

There were no injuries in the fire that broke out around 8:30 p.m. ET on the campus in Knoxville, Tennessee, whose buildings were boarded up to prevent break-ins and fires, said Knoxville Fire Department Deputy Chief Mark Wilbanks.

“This building is probably over 100 years old. “It has completely collapsed and is a total loss,” Wilbanks said at the scene of the fire, video from NBC affiliate WBIR in Knoxville showed.

The cause of the fire was not yet known Monday evening, he said.

Knoxville College is a small HBCU (historically black college or university) founded in 1875.

In 1997, it lost its national accreditation due to declining enrollment. The state allowed it to resume classes in 2018, but they were online, the Knoxville News Sentinel reported in July, as the school seeks to regain its accreditation.

Buildings on campus have been boarded up, including the former administration building that burned Monday, and there have been break-ins and fires on campus in the past, Knoxville Mayor Indya Kincannon said at the scene.

“It’s just a sad day for our city,” Kincannon said.

Frank Shanklin Jr., a member of the Knoxville College Board of Trustees, told WBIR that the former administration building has not been used for the past 40 or 50 years.

“We will continue to fight for Knoxville College,” Shanklin said, adding he hopes the city, county and people of the area keep this in their prayers. “We will fight to get the college reopened.”
