Block of Aquia Creek sandstone removed from the East Front of US Capitol

Enslaved African Americans, leased out by their slave owners, mined sandstone from local quarries and built the United States Capitol, the White House, and the Smithsonian Castle. Congress, the institution that guarded the peoples’ freedom, held sessions in a building constructed by forced labor, and the legislators would have witnessed lines of shackled slaves marching by daily en route to the Deep South. The block was quarried near Aquia Creek, Virginia, by free and enslaved workers and used in the construction of the Capitol building in 1824.
