On November 17, 1800, the United States Congress met for the very first time in the as-yet-unfinished Capitol building in Washington, D.C.
President George Washington had laid the cornerstone in 1793, launching a years-long construction project that employed many enslaved laborers.
Completed in 1826, the original Capitol soon proved too small for the growing nation.
And so, in 1855, construction began on a vastly expanded building with a towering new dome.

Work on the Capitol continued even through the darkest days of the Civil War. Said President Abraham Lincoln, "If people see the Capitol going on, it is a sign we intend the Union shall go on."
The dome was completed, and topped off with an idealized "Statue of Freedom," in time for Lincoln's second inauguration in 1865.
