Upside-down Christmas tree, UK, by Shirazeh Houshiary
Artist Shirazeh Houshiary designed this upside-down Christmas tree for London's Tate Britain in 2016, which was hung from the ceiling of the gallery's Millbank building.
Houshiary covered the roots in gold leaf to highlight a part of the pine tree that is usually hidden while embracing the natural texture, colour, shape and smell of the rest of the tree.

Frozen Christmas tree, UK, by Alex Chinneck
In 2016, British artist Alex Chinneck seemingly froze a Christmas tree in a giant ice cube for this installation at King's Cross in London.
Chinneck used a two-tonne block of resin to confine the five-metre-tall Christmas tree and added a surrounding puddle of wax to give the appearance of melting ice.

Architecture practice Sam Jacob Studio aimed to create a futuristic interpretation of Christmas trees when designing Electric Nemeton, a display at Granary Square in London's King's Cross made up of elevated obelisks.
