WASHINGTON (AP) — A world-famous symbol of democracy is going under cover, as workers start a two-year, $60 million renovation of the U.S. Capitol dome.

Curved rows of scaffolds, like Saturn’s rings, will encircle it next spring, enabling contractors to strip multiple layers of paint and repair more than 1,000 cracks and broken pieces. The dome will remain illuminated at night and partly visible through the scaffolding and paint-capturing cloths. But the Washington icon — and portions of the Rotunda’s painted ceiling that lies below — will be significantly obscured for many months.
