On September 18, 1793, a defining moment for the fledgling United States took place: President George Washington laid the cornerstone of the U.S. Capitol. What began as a symbolic act quickly evolved into a saga of architectural ambition, political turmoil, and national identity.
In the years following the Revolutionary War, the United States had no fixed seat of government. Congress shuffled between meeting places like New York, Philadelphia, and Baltimore. In 1790, Congress passed the Residence Act, granting President Washington authority to select a site for a permanent capital. He chose land ceded by Maryland and Virginia, which soon became the District of Columbia.
Washington appointed three commissioners to oversee development and commissioned French engineer Pierre Charles L’Enfant to lay out the city. However, L’Enfant’s vision and temperament eventually clashed with the commissioners’, leading to his dismissal in 1792. After a design contest, William Thornton, a Scotsman, won with his proposal for the Capitol building.
On the appointed day—September 18, 1793—George Washington, amid ceremony, laid the cornerstone of what would become an enduring symbol of American democracy. Construction officially began, though progress would be slow and sporadic.
The Capitol’s story is far from linear. Over its nearly century-long construction, it survived setbacks like the War of 1812, when British troops burned parts of Washington, D.C., including the Capitol. Congress was forced to meet elsewhere while the structure was rebuilt.
Growth pressures of a young and expanding nation led to additions: wings for the House and Senate, expansions in the mid-1800s, and later the imposing cast-iron dome that dominates the skyline today. During the Civil War, the Capitol itself even played roles beyond the legislative—serving for a time as a hospital and barracks.
Today, the Capitol is more than just an iconic building. It is the hub of the legislative branch of the U.S. government, surrounded by the Capitol Complex, which includes multiple congressional office buildings, the Library of Congress, and an expansive collection of American art. It’s nearly 540 rooms that cover about four acres and draw millions of visitors annually.
The laying of the cornerstone in 1793 stands not simply as a construction milestone but as an act rich with meaning: the planting of roots for democracy, governance, and public identity. It signified the resolve of a nation in its infancy to build something lasting, something grand, and something symbolic—and over two centuries later, the United States Capitol remains just that.
