Firefighters responded to a fire in Grapevine Friday morning at a historic two-story home.
The fire started at about 4 a.m. on the 500 block of Wildwood Lane.
Crews quickly called for a second alarm due to the heavy flames.
The home collapsed as firefighters battled the blaze.
A man and woman were in the home at the time of the fire. They escaped without injuries.
Police say the home was built in the 1860s and was the first postmaster of Grapevine.
Investigators are working to determine the cause of the fire.
