Fort Worth firefighters battle blaze at historic Public Market building on Henderson St.

A fire Thursday night damaged the 93-year-old Public Market building on Henderson Street, a historic structure that the fire department called a staple of downtown Fort Worth.

Just before 8 p.m., the Fort Worth Fire Department received multiple calls about black smoke coming from the vacant building at 1400 Henderson St., the department said in a Facebook post.

Firefighters found flames on the first floor of the building.

“Thankfully, firefighters were able to keep the fire contained to the interior of the building and prevented it from spreading and damaging the terra cotta exterior or the structural integrity of the building completely,” the fire department said.

The market was added to the Texas Historical Commission Landmark list in 1980 and the National Registry of Historic Places in 1984.

About 30 minutes into the operation, the incident commander requested a second alarm. Additional companies responded to provide relief for firefighters in the triple-digit heat. In total, 75 fire personnel responded over the course of two and a half hours.

There were no injuries. The cause of the fire is under investigation.
