The United States Capitol was built by enslaved laborers and once hosted Sunday church

In short: The U.S. Capitol is more than a legislative seat; it is a layered monument of shifting architectural styles and complex history. From its origins as a pedestal for a monument to its role as a temporary church, the building reflects the evolving identity of the nation it houses.

The Capitol’s construction was a fraught process defined by design competitions, architectural disputes, and the reliance on enslaved labor. When the federal government moved to Washington in 1800, the building was incomplete, and the House and Senate shared quarters in the north wing. The project faced constant setbacks, including the 1814 burning by British forces and persistent shortages of free craftsmen. To fill this labor gap, the government hired enslaved people from Maryland and Virginia, paying their owners between $55 and $65 annually while providing basic rations and housing.

Architecturally, the building is a palimpsest of neoclassical ambition. While the original design by amateur William Thornton was praised for its beauty, it was repeatedly altered by figures like Benjamin Henry Latrobe and Charles Bulfinch. The iconic cast-iron dome, completed around 1866, was a response to the building’s 1850s expansion, which dwarfed the earlier, smaller dome. This massive structure, weighing over 8.9 million pounds, was designed by Thomas U. Walter to echo European landmarks like St. Peter’s Basilica and the Paris Pantheon.

Beyond its political function, the Capitol served as a public space for religious life. For decades, the House chamber hosted nondiscriminatory Sunday services attended by presidents including Thomas Jefferson and James Madison. Today, the building continues to evolve, from the 2008 opening of the underground Visitor Center to the 2014 restoration of its brittle iron dome. Even its discarded remnants have a second life; original sandstone columns removed during a 1958 expansion were repurposed as a monument at the National Arboretum, while smaller stone blocks have been sold as commemorative bookends.
