Soil has been used by mankind throughout its history as a tool for self-expression. Cave paintings, one of the oldest art forms in existence, were created using soil, while nowadays soil is reflected across many art forms – videos, paintings, installations – even music and poetry. Soil has also been critical in shaping our national history and culture – from the colours and shapes of our landscapes to the raw material for our buildings and the varieties of food we grow from one region to the next.
