The Peace Monument is a contemporary sculpture in Bicentennial Park at Homebush Bay. It was commissioned to celebrate the International Year of Peace in 1996. The layout is based on a complex interplay involving the Earth’s axis and the trajectories followed by the planets in our Solar System. It illustrates what it might be like to be out in space looking back at earth to remind us of our fragile place in the solar system. Because we don't feel or see the earth turning, we are rarely conscious that we live on a sphere constantly spinning through space. Throughout history, bells have been rung to celebrate the achievement of peace. There are three bells here for The Earth, The Moon and Space.
