Tate Modern unveils Turbine Hall work by Abraham Cruzvillegas
Twenty-three tonnes of soil from around London, including from Buckingham Palace, have gone on display at London's Tate Modern.
The artwork by Mexican sculptor Abraham Cruzvillegas is called Empty Lot and is the latest exhibition in the Tate's huge Turbine Hall.
Under horticultural lighting the soil will be watered every day to see what might sprout through the dark days of an English winter.
The work echoes Cruzvillegas' own community in Mexico city in which people built their own homes and gardened any spare patch of land.
