Begun in 1793 and expanded repeatedly, the U.S. Capitol integrates neoclassical wings, a cast‑iron dome (1860s), and the Rotunda’s civic art. The Architect of the Capitol stewards structure, finishes, and grounds while balancing security, legislative operations, and tourism. Recent restorations cleaned and stabilized the dome and masonry, preserving a national symbol of governance.
From early competitions to additions by Latrobe and Bulfinch, the building’s plan grew with the nation. Mid‑19th‑century extensions housed a larger Congress.
The cast‑iron dome, crowned by the Statue of Freedom, replaced an earlier wood‑covered version. Iron ribs, plates, and meticulous painting define a landmark silhouette.
The Architect of the Capitol manages conservation, from stone repointing to art care, alongside layered security that protects legislative work and visitors.
Tours route through the Capitol Visitor Center to manage queues and interpret history with exhibits and films.
