The latest in the celebrated Unilever Series of commissions for the Turbine Hall has been undertaken by Rachel Whiteread. For the Turbine Hall, she has created a gigantic labyrinth-like structure, entitled EMBANKMENT, made from 14,000 casts of the inside of different boxes, stacked to occupy this monumental space. The form of a cardboard box has been chosen because of its associations with the storage of intimate personal items and to invoke the sense of mystery surrounding ideas of what a sealed box might contain.
