via The Nation, 19 August 2022: The Fine Arts Department prepares for flood season in Ayutthaya.
More than 100 soldiers and officials from the Fine Arts Department put up the 2-metre-high metal planks that can be raised or laid flat. The planks cover a distance of 165 metres around the temple, which sits on the west bank of the Chao Phraya River.
Sandbags were also laid in front of the levee to slow down water flow and a wall of scaffolding will also be put up behind the level to strengthen it.
