Police are investigating the cause of a fire that engulfed a 20-year-old teak residence for monks at Wat Pa Pha in Mae Hong Son's Sob Mei district on Sunday night.
No one was injured.
The blaze started at about 8.30pm and also burnt a century-old Buddha statue made of fragrant wood and some Bt100,000 in cash donations.
Abbot Phra Kru Anurak Pattanakhun told police that he and other disciples were performing an evening prayer at the ubosot when they heard someone shout that there was a fire.
He said the whole building was on fire and the monks tried to extinguish the blaze using buckets of water while waiting for firefighters to arrive.
The blaze spread fast as the whole building and statues inside it were made of wood.
The building was engulfed within 30 minutes.
