The dome of the Rotunda at the University of Virginia in Charlottesville has been through a lot: the terne-coated steel roofing was in poor shape, there were leaks, and iron tension rings that secured the dome's shape were corroded. A $50.6 million renovation is under way and will restore the dome as nearly as possible to its original appearance. Copper will replace the steel and be painted white. Ventilation underneath will be added to prevent rust.
