The Capitol Dome in Washington will be completely repainted

The restoration, which will be completed only in September, will require about 2,200 gallons of paint, said Eva Malecki, the spokeswoman for the Architect of the Capitol (AOC), the federal agency responsible for maintaining the Capitol.

Starting Monday, scaffoldings will be mounted on the giant dome built in the neoclassical style of American capital.

AOC will also try to evaluate the needs for a full restoration of the building, which is the iron armature.

“The last significant renovation of the exterior dome dates from 1959-1960, when it was stripped of paint to treat the iron structure with a product against rust,” said the agency.

The current Cathedral was built between 1855 and 1866 and the bronze statue placed on top, symbolizing liberty, was installed in 1863.

Initially, the Capitol dome was smaller, made of wood and copper. Its construction was completed in 1824. In 1850, however, it was considered too vulnerable to a possible fire and was decided to build a bigger, more resilient dome.
