A Unesco World Heritage site has been subjected to fire damage following a blaze in the Ayutthaya province.
The building, which is part of an old royal palace in Wat Phra Sri Sanphet was built mainly from wood and had been used for educational purposes since 2015, providing information about the ancient capital of Siam.
The fire commenced on Sunday evening around 21:30. Firefighters extinguished the flames within 30 minutes but serious damage had been inflicted on the building. Damage estimates of over three million baht have been reported.
At first the fire was believed to have been caused by an electrical fault but officials from the Fine Arts Department informed authorities that there had been no electric supply since August 2016.
A full investigation will take part to determine the cause of the fire.
