 The exhibition remained open to the public until 2005, when it was closed for a third restoration. The $ 12-million restoration, by Olin Conservation, Inc., of Great Falls, Virginia, started with the 26 sections of the painting and recreated its original shape of 14 panels hung from a circular railing, slightly flared out at the bottom. In the process, some original pieces were found of the 12 circumferential feet that had been cut away. Fourteen vertical feet of sky was also restored.
