The caisson (Chinese: 藻井; pinyin: zǎojǐng; lit. 'algae well'), also referred to as a caisson ceiling, or spider web ceiling,[1] in Chinese architecture is an architectural feature typically found in the ceiling of temples and palaces, usually at the centre and directly above the main throne, seat, or religious figure.[1][2] The caisson is generally a sunken panel set into the ceiling. It is often layered and richly decorated. Common shapes include squares, octagons, hexagons, circles, and a combination of these.[3]
