A pair of decorated ceilings in the main Central Hall (officially Hintze Hall since 2014) and smaller North Hall of the Natural History Museum in South Kensington, London, were unveiled at the building's opening in 1881. They were designed by the museum's architect Alfred Waterhouse and painted by the artist Charles James Lea. The ceiling of the Central Hall consists of 162 panels, 108 of which depict plants considered significant to the history of the museum, to the British Empire or the museum's visitors and the remainder are highly stylised decorative botanical paintings. The ceiling of the smaller North Hall consists of 36 panels, 18 of which depict plants growing in the British Isles. Painted directly onto the plaster of the ceilings, they also make use of gilding for visual effect.
