A tree cathedral is an arboretum laid out so the arrangement of the trees creates the typical architectural elements of the nave, chancel, and transepts usually constructed from masonry in a typical medieval cathedral. Examples of tree cathedrals include:
Whipsnade Tree Cathedral in Bedfordshire, England. It was planted from 1932 by the lawyer Edmond Blyth as a First World War memorial, inspired by Liverpool Anglican Cathedral. It was donated to the National Trust in 1960, and became a Grade II registered garden in 2017. The tree cathedral planted 1986 at Newlands, near Central Milton Keynes, to a design by the landscape architect Neil Higson, based on Norwich Cathedral. De Groene Kathedraal, Almere, Netherlands, based on Reims Cathedral The cattedrale vegetale at Malga Costa, in the Val di Sella in northern Italy, a project commenced in 2001 (see Arte Sella), and a second one at Lodi, Lombardy, for Expo 2015; both by the Italian artist Giuliano Mauri.
