A Capitol Idea

If you’ve ever wanted to have a fun vacation, visit Washington D.C., and especially visit the U.S. Capitol Building. The first time I saw it in person, I have to admit it was a breathtaking moment: that giant grand dome rising above the National Mall, white marble, long steps majestically framed by a blue sky and fluttering flags. When Jackie and I took the girls to DC to explore, we made sure to visit the capital. We were able to witness a vote taking place – (fascinating to see the various congress people meandering in to place their vote, then leave – and watching the tabulations taking place on the wall was very interesting as well). Historians say the US Capitol Building is the centerpiece of American history, drama, innovation, politics, art, personalities, and quirky architectural decisions – a place where the ideas and contradictions of the nation are literally set in stone. Did you know, our American flag flies continuously at the east and west bases of the dome — day and night since World War I. Flags over the Senate (north) and House (south) wings fly only when the chamber below is in session, and hidden flagpoles handle special ceremonial requests. I did some digging (SO MUCH info!) about this great building, its varied history, and quirks you might find interesting. Be sure to get a trip in to visit, and think about our great nation, and all that’s come before us. Enjoy!

A Monument Worth Building 

Long before the Capitol was ever sketched on paper, the United States Congress wandered from city to city. Early federal meetings happened in Philadelphia, New York City, Annapolis, Maryland, Princeton, and Trenton, New Jersey. In fact, a 1783 protest known as the Pennsylvania Mutiny forced representatives to flee Independence Hall and seek safety elsewhere. It became painfully clear: the nation needed a permanent capital.

The Residence Act of 1790 settled the issue and picked a site along the Potomac River. Enter Pierre L’Enfant, the visionary planner who laid out Washington, D.C. In his grand design, Capitol Hill would be the literal high point of the city — “a pedestal awaiting a monument.” L’Enfant called the building the “Congress House,” but another founding father, Thomas Jefferson, suggested a new name: the Capitol — inspired by Rome’s Capitoline Hill, home of the Temple of Jupiter. (Capitol means the building; capital means the city.)

Construction began on September 18, 1793, with President George Washington laying the cornerstone surrounded by Masonic ritual. The original plans were the result of a design competition – an unusual move in early America. The winning entry came from William Thornton, an amateur architect praised by Washington and Jefferson for its “Grandeur, Simplicity, and Beauty.” Thornton’s design impressed not because it was perfect, but because it was visionary at a time when few Americans had formal architectural training.

Changing Architects, Changing Times

Thornton set the tone, but the Capitol was never built by just one hand. Benjamin Henry Latrobe, known as the Father of American Architecture, redesigned the interiors, added innovative structural features, and redesigned the Supreme Court and Senate chambers. Like most major projects, he faced constant disagreements with government officials — and quit more than once.

Charles Bulfinch took over from Latrobe for a time and oversaw early interior design and constructed the first low, copper-covered dome. In the 1850s, as the nation burst westward with new states, the Capitol needed to grow. Thomas Ustick Walter. stepped up and designed the great cast-iron dome, proportional to the sprawling new wings. This is the dome we recognize today – taller, heavier, and far more intricate than the original. Of note, the dome is not stone – it’s cast iron, weighing in at nearly 9 million pounds, supported by the original masonry piers, and crowned with a statue called the Statue of Freedom.

Fire, War, and Resilience

The Capitol’s early years were tumultuous: During the War of 1812, British forces marched into Washington and set fire to government buildings, including the Capitol. The rotunda was gutted, walls blackened, and the roof destroyed. Congress didn’t abandon the building for long, though. Reconstruction began almost immediately. The commitment to rebuild was a statement: the experiment of self-government would survive.  The Capitol’s survival became a symbol, not just bricks and mortar. Legend has it that a sudden thunderstorm stormed in just as the British were burning the building — and might have helped prevent total destruction. 

Wings and Chambers

Originally, the Capitol had two small wings: the North, housing the Senate Chamber, and the South, with the House Chamber. As states joined the Union, both chambers outgrew these spaces. By the 1850s, massive expansions doubled the building’s footprint: A new Senate wing to the north and A new House wing to the south, and the grand, cast-iron dome. Under these expansions, the building became more than a meeting place — it became a sculpture of democracy, constantly adapting to the nation it housed.

Paintings, Frescoes, Statues, and Stories

The Capitol’s interior is a museum of American memory. The Rotunda is The Apotheosis of Washington, it is a fresco by Constantino Brumidi painted 180 feet above the floor  

It depicts George Washington rising toward the heavens, surrounded by Roman gods and symbols. Brumidi also designed the Frieze of American History, a chronological visual record from Columbus to the Wright Brothers (completed by four artists over nearly 80 years) and hallways with portraits of founding figures and symbolic flora and fauna. Large canvases depict the Declaration of Independence, Surrender of Cornwallis, and more. Brumidi intentionally left blank spaces for future events, which means the artwork literally grows with our history. And the National Statuary Hall houses two statues from each state — from presidents to pioneers. 

Fun Fact: A statue of King Kamehameha from Hawaii had to be moved to Emancipation Hall because it weighed 15,000 pounds too heavy for the floor it was intended to occupy!

Secrets, Oddities, and Capitol Curiosities

Once you step beyond the grand rotunda, the Capitol gets delightfully quirky. Some tiny doors around the Capitol are barely 30 inches tall — not for legislators, but for hidden water spigots and service access. These doors were part of a fire-prevention system installed after the Christmas Eve fire of 1851 – a system now retired, but the doors remain. 

Secret Tunnels & Subways include underground passageways that connect the Capitol to office buildings – a perfect hideaway from rain, heat, crowds, and reporters alike!

The staircase to the top of the dome has 365 steps — exactly one for each day of the year. Climbing it is like stepping through a calendar of history.

In the Capitol basement once sat: Spa-like Senate baths, A barbershop, and a massage parlor. These have mostly vanished, but a pair of marble bathtubs remains as a reminder of a gentler era of lawmaking.

A Living Symbol, Still Under Construction

From its beginning in 1793 to today, the U.S. Capitol isn’t a static monument. It’s a living building. It’s been enlarged and reinforced, painted and re-painted, rewired for modern technology, and constantly under construction.
