"It fell a year ago and now 364 days later we put it back up," Tom Sater, a restoration consultant, said.
The chandelier fell five feet in November 2006 after being lowered from the dome for routine maintenance.
The cable holding the chandelier became stretched over night and the light fixture fell.
"It was more of a rapid controlled descent," Sater said. "It rode the cable, so it didn't free fall."
The bottom of the chandelier was crushed. The fixture had to be dismantled and several parts including the winch and cable systems, had to be restored.
"It affected other parts and then we found other problems like stripped bolts," Sater said.
The chandelier was created in 1918 by Guth Lighting company is St. Louis for $5,000. The capitol dome is 238 feet high.
Sater said the repairs cost more than $500,000 and took so long because the restoration was done by a different company.
Part of the restoration included turning on the highest level of lights which have not been illuminated since the late 1960s. The lights were causing damage to the mural in the interior of the dome which degraded the color almost 50 percent Sater said.
When the lights turned on Wednesday observers gasped as a mural lining the top of the dome and shadowed by ineffectual lighting for 40 years was depicted in full light.
"Everyone who's been here 30 or 40 years is standing here saying, oh my god," Sater said.
