Since 1988, each year Tate Britain has commissioned an artist to produce a Christmas tree for its foyer. This year, it's the Iranian artist Shirazeh Houshiary's turn. Rather than go heavy with the tinsel (or fairy genitals, as was the case with Sarah Lucas), she's left her pine completely bare and given it just a few simple touches: flipping it upside-down, covering its exposed roots in gold leaf and suspending it from the ceiling.
Unusually, it's not the first time Houshiary has shown the piece: this first made an appearance back in December 1993. But that was many years before Caruso St John's £45 million renovation of the gallery, which added a new spiral staircase in the rotunda space. So it's nice to see her elegantly sparse sculpture in this fancy new setting.
Shirazeh Houshiary's Christmas tree will be on display at Tate Britain throughout the festive period. Obviously.
