The north wing is where the Senate meets. The south wing is where the House of Representatives meets. These wings are also known as chambers.

History of the Capitol Building

The first capital city of the United States was New York City. From 1785 to 1790, Congress met there in a building called City Hall. Then, the capital moved to Philadelphia, Pennsylvania. From 1790 to 1800, Congress met in the Philadelphia County Building. In 1800, the capital moved again to Washington, D.C.. A new Capitol building was built there.

The Capitol was designed by a person named William Thornton. Building work started in 1793. However, it took almost 20 years for it to be fully finished. The Senate started using their wing of the Capitol in 1800. The House of Representatives began meeting in their wing in 1807. Their wing was not fully ready until 1811.

At first, the Capitol was smaller than it is today. The dome in the middle was made of wood and was not as large. In 1814, during the War of 1812, the British Army set the Capitol on fire.

In the 1850s and 1860s, the Capitol was fully repaired. The old wooden dome was replaced with a much larger iron dome. Many murals were painted on the walls of the Senate wing. These paintings showed important moments in American history. A large fresco was also painted on the ceiling inside the Rotunda during these repairs.

The Supreme Court, which is the highest court in the U.S., also met in the Capitol. They stayed there until their own building was finished in 1935.

The Capitol Dome is very heavy, weighing about 8,909,200 pounds (4,009 tonnes). It is made of cast-iron and has 108 windows. It was built between 1855 and 1866.

On January 6, 2021, a large group of people entered the Capitol building. This event caused the building to be put on lockdown for safety.
