The Dupont Plaza Hotel fire was a fire that occurred on the Hotel Dupont Plaza (now San Juan Marriott Resort & Stellaris Casino) on New Year's Eve, December 31, 1986.
The fire was initiated by three disgruntled employees of the hotel that were in the middle of a labor dispute with the owners of the hotel. In the end, the fire claimed 97 lives and caused 140 injuries.
This is considered to be the most catastrophic hotel fire in Puerto Rican history.
