A lightning strike caused a home on Thompson Street in Glastonbury to burst into flames last Wednesday night, according the fire marshal's office.
Fire had engulfed the house when crews arrived on scene, and the flames were so intense that firefighters were not able to get inside.
No one was home when the fire started, according to fire officials, and no injuries are reported.
The home is in an area with no fire hydrants, so crews needed to bring in water and several towns sent mutual aid, including Colchester, Marlborough, Portland and Hebron.
The fire broke out as severe thunderstorms rolled through the area.
A home in Warren was also struck by lightning that day.
