United States Capitol dome, Neoclassical dome at United States Capitol, Washington, D.C.
The cast iron dome rises 288 feet above the Capitol building, featuring both an inner and outer structure with a combined weight of 9.1 million pounds.
Constructed between 1855 and 1866 under architect Thomas U. Walter, the dome replaced an earlier copper-covered wooden structure designed by Charles Bulfinch.
The interior of the dome displays Constantino Brumidi's fresco 'The Apotheosis of Washington' at its apex, depicting the first president ascending to the heavens.
Regular maintenance of the dome includes repairs to prevent water infiltration, rust removal, and repainting to protect the cast iron structure from environmental damage.
The dome's construction continued throughout the Civil War, with President Lincoln insisting that its completion would signal the nation's persistence through conflict.
