(KRON) — A major structure fire Sunday evening at The Well shopping center in Livermore destroyed at least three buildings and damaged two others, according to the Livermore-Pleasanton Fire Department.

Livermore-Pleasanton FD responded to the shopping center blaze at Holmes Street and Concannon Boulevard at around 5:13 p.m., officials said. Three abandoned buildings were “a total loss,” Battalion Chief Greg Kurtz said. One nearby restaurant, Charming Fig, suffered moderate damage in the three-alarm fire, and another abandoned building in the area was also damaged.

Two firefighters were treated for minor injuries and released by medical personnel, according to officials.

Fire crews continued to monitor and put out hot spots overnight and into Monday.

The cause of the fire is currently unknown, Testa said. LPFD and the Livermore Police Department are investigating the cause and origin of the fire as of Monday morning, Kurtz said.

Holmes St. and Concannon Blvd. were closed in the area as the fire department battled the fire. Both roads were reopened as of 9:30 p.m. Sunday night.
