Massive fire destroys historic Ambassador Hotel in Dallas

DALLAS, Texas (KTRK) -- A huge fire destroyed the landmark Ambassador Hotel early Tuesday morning.

Authorities say it took 100 firefighters to put out the 4-alarm fire.

The building was vacant and no one was hurt.

Authorities don't know what started the fire, but firefighters are looking closely at some nearby powerlines. It appears a transformer exploded.

The hotel was built in 1904. It became a Texas landmark 60 years later. It was being transformed into apartments with shops, restaurants, a swimming pool and a speakeasy bar.
