On display at these facilities will be 28 exhibitions and 24 activities that pay tribute to the late king, who passed away on October 13.

Under the special “Night at the Museum” project, 16 museums will operate from 8am to 10pm between December 16 and 18 in his honour.

Participating museums include Museum Siam, Rajdamnoen Contemporary Art Centre, the Queen’s Gallery, Rattanakosin Exhibition Hall, King Prajadhipok’s Museum, Bangkok Planetarium, and Art in Paradise Bangkok.

Meanwhile, the Culture Ministry has completed three sets of photo collections on the royal funeral of the late monarch.

“Each set has three volumes – one featuring events in Bangkok, another featuring events in provinces, and the other featuring events overseas,” Culture Minister Vira Rojpojanarat said yesterday.

He said 480 photographers had contributed to the compilations, a quarter of them professionals who volunteered their services for the task.

This combined with many people and organisations that submitted photos to the National Archives of Thailand.

Vira said many of these photos had already been selected for exhibitions in honour of the late king.

Mobile exhibitions will be staged at venues across the country. For example, one exhibition will be held in Lop Buri province from December 19 to 27.

“A photo exhibition has also been held in Bhutan between December 8 and 10,” the minister said.

Nantaka Phonlachai, acting chief of the National Archives of Thailand, said this was the first time her agency had gathered such complete information and photos through collaboration from all sectors.

“Volunteers from the people’s sector, in particular, have helped record all the events that happened in their areas and sent their recordings to us,” she said.

The archives agency had expected to receive contributions from all sectors till the royal funeral ceremonies ended.

“We believe the process will be year-long but everyone is willing to support our work,” she said.

Nantaka advised contributors to not heavily edit their photos, particularly by using black-and-white or sepia mode.

“We will put in our archives the photos that can tell stories,” she said.
