British artist Andy Goldsworthy, along with his assistant and a team of workers including four dry-stone wallers also from Britain, installed the sculpture entitled 'Roof' on the ground level of the East Building over the course of nine weeks in the winter of 2004/2005. The sculpture comprises nine, stacked-slate, hollow domes, each measuring approximately five and a half feet high and twenty-seven feet in diameter.
