A fire at the Thai Film Archive temporary office in Nakhon Pathom province on Sunday night caused only limited damage to historical footage, and there are copies of all the films, the organisation announced on Monday.
A statement posted on its Facebook page said the fire was at its temporary office, and not at a main film storage facility. The office stored only a small number of films due for examination.
Some old and nitrate films were kept there, but there were copies, including digital ones, the Thai Film Archive announcement said.
No one was injured and police were investigating the cause of the fire.
Day to day operations were not affected and visitors were welcome from Tuesdays to Sundays as usual, it said.
The fire was reported to have started on the upper floor of the two-storey temporary office made from modified cargo containers, in tambon Salaya of Buddha Monthon district, about 7pm on Sunday.
Fire crews took about an hour to extinguish the blaze, which destroyed films held at the facility.
The Thai Film Archive has been a public organisation since 2009. Prior to that it was under the Fine Arts Department.
