The fire responsible for the destruction of the Texas Governor’s Mansion is thought to have been intentionally caused by someone.

According to The Associated Press, fire investigators said that the evidence in the case indicated that the fire was “intentionally set.” Fire Marshal Paul Maldonado didn’t say how the fire was set or if there was a suspect, but informed that arson was suspected.

Thanks to some surveillance cameras, the investigators can find out more about the fire. The authorities also asked the public to provide information about the fire.

Governor Rick Perry and his wife moved out of the house last fall as it was undergoing a massive $10 million renovation, and there were no people present at the time the fire broke out.

The governor’s spokesman Robert Black said that the longleaf pine that was inside the mansion was “completely irreplaceable” and that some of the ornaments suffered important damage, reported The Associated Press.

As most of the mansion’s items were stored away for a better access in its undergoing renovation process, the historic paintings and some of the furniture managed to escape the fire. More than 100 firefighters, pumping about 6,000 gallons of water a minute, helped put down the fire.

According to Black, the damage inflicted on the mansion "is extraordinary, bordering on catastrophic," as quoted by the Associated Press. Apparently, the top floor was completely destroyed and part of the ground floor was heavily wrecked.

The mansion, a national historic landmark, was built in 1856 and since then it has been the home of every named state chief executive.
