USA Capital Overview
The United States Capitol is a magnificent building with a rich history. It's located in Washington, D.C.
The Capitol has undergone several transformations since its construction began in 1793. The original design was by William Thornton, but he had no knowledge of building technology, so the construction was initially supervised by Stephen Hallet, the runner-up in the competition.
The north wing, containing the Senate chamber, was completed first, in 1800. The south wing, containing the House of Representatives, was completed in 1807. The Capitol was later looted and burned by British troops during the War of 1812, but it was rebuilt and expanded over the years.
Here are some key facts about the Capitol's expansions:
- The south wing was extended in 1857 and the north wing in 1859 by architect Thomas Ustick Walter.
- The extensions provided more space for the increasing numbers of legislators from new states.
United States
The United States Capitol is a magnificent building, but its construction was a bit of a challenge. The initial supervisor, Stephen Hallet, tried to alter Thornton's plans, but he was quickly replaced by George Hadfield and then James Hoban, who designed the White House.
The north wing, containing the Senate chamber, was completed first, and Congress convened there in November 1800. The building's unique Corinthian-style columns, designed by Benjamin Latrobe, feature capitals depicting tobacco leaves and corn cobs.
The Capitol was looted and burned by British troops during the War of 1812, but Latrobe began reconstruction in 1815. Unfortunately, he resigned two years later, and it took Charles Bulfinch until 1827 to join the two wings and build the first copper-sheathed dome.
The Capitol's design has undergone several changes over the years. In 1850, Congress approved a competition for a design to expand both wings, and the winner, Thomas Ustick Walter, finished the extension of the south wing in 1857 and the north wing in 1859.

History
The Capitol building in Washington, DC, has a rich history dating back to the late 1700s.
Pierre Charles L’Enfant, a French engineer, designed the new capital city, and he envisioned the Capitol building as the most important structure, situated on Jenkins’ Hill, now known as Capitol Hill.
A design competition was held, but none of the 17 entries pleased the judges. That was until Dr. William Thornton submitted a neoclassical design, which was immediately approved.
The Capitol building was constructed with the help of enslaved people, who worked on quarrying stone and carving columns.
In 1800, the government moved into the building, which originally housed not only the House and Senate but also the Library of Congress and the Supreme Court.
The British burned the building in 1814 during the War of 1812, but it was rebuilt and continues to stand proud today.
The Capitol building has undergone changes over the years, with the Library of Congress and the Supreme Court relocating to nearby buildings in 1897 and 1935, respectively.
Today, the Capitol building remains a grand and historic tribute to American democracy.

Rebuilding Post-War
The Capitol Building was torched by the British during the War of 1812, but a fortuitous rainstorm prevented its total destruction.
Benjamin Latrobe was hired to oversee the rebuilding of the Capitol, but he was eventually replaced by Charles Bulfinch in 1818.
Bulfinch completed the areas of the building that accommodated the House, Senate, and Supreme Court, and he designed and built the Capitol's original wooden dome.
The Capitol Building took a lot of damage, but it's amazing to see how it was rebuilt and restored over the years.
Design and Architecture
The Capitol's design and architecture are truly breathtaking. The 1850 expansion more than doubled the length of the building, making the original dome look tiny in comparison.
The original dome, designed by Charles Bulfinch, was a copper-sheeted, low dome that was no longer in proportion with the increased size of the building. It was eventually torn down and replaced with the iconic cast-iron dome designed by Thomas U. Walter.
Walter's dome is a masterpiece, standing three times the height of the original dome and 100 feet in diameter, yet it's supported on the existing masonry piers. The dome's cast iron frame weighs a staggering 8,909,200 pounds.
The dome's design draws inspiration from other notable buildings, including the dome of St. Peter's Basilica in the Vatican and St. Paul's Cathedral in London.
Dome
The Capitol dome is a stunning feature of the United States Capitol building, and it's worth taking a closer look.
The original dome, designed by Charles Bulfinch in 1818, was replaced in 1855 with a new, cast-iron dome designed by Thomas U. Walter. This new dome stands three times the height of the original and is 100 feet in diameter.

The new dome is a masterpiece of engineering, weighing in at 8,909,200 pounds of cast iron. It's supported by existing masonry piers and features a large oculus in the inner dome, through which you can see The Apotheosis of Washington painted on a shell suspended from the supporting ribs.
The dome's design was influenced by Mansart's dome at Les Invalides in Paris, which Walter had visited in 1838. This is evident in the double dome structure and the use of a tholos to support the Statue of Freedom.
The Statue of Freedom, a colossal statue that was raised to the top of the dome in 1863, invokes the goddesses Minerva or Athena. It's a fitting tribute to the building's rich history and symbolism.
The cast iron for the dome was supplied and constructed by the iron foundry Janes, Fowler, Kirtland & Co. The thirty-six Corinthian columns that surround the base of the dome were provided by the Baltimore ironworks of Poole & Hunt.
The dome's massive visual weight has had an impact on the surrounding architecture, overpowering the proportions of the columns of the East Portico, built in 1828.
The Rotunda
The Rotunda is a grandiose space that's the heart of the Capitol building. It's where both sides of Congress come together to celebrate new bills or receive esteemed visitors.
This impressive room is also where important people lie in state or in honor, with only 40 individuals holding this distinction so far. Abraham Lincoln, Ruth Bader Ginsberg, and two Capitol police officers killed in the January 6 insurrection are among those who have been honored in this way.
The fresco inside the dome above is a stunning piece of art, titled "Apotheosis of Washington" and created by Constantino Brumidi. It depicts George Washington in the heavens, surrounded by the goddesses Liberty and Victory, and 13 maidens representing the original 13 colonies.
Four revolutionary period scenes and four scenes of early exploration decorate the walls, adding to the Rotunda's sense of history and grandeur. Most of the statues and busts are of presidents, including a notable sculpture of Abraham Lincoln by Vinnie Ream, the first woman artist to receive a federal government commission.
The Rotunda's unique acoustic effect is also worth noting, as it amplifies the voice of a speaker so that it sounds as though they're standing right next to you, even if they're yards away. This makes it an ideal space for speeches and other important announcements.
