Building a More
Perfect Union

This online exhibition for the U.S. Capitol Visitor Center examines the story of the Capitol during the years surrounding the Civil War. Throughout this important period in our country’s history—and continuing into today—the Capitol remains an enduring symbol of our nation’s unity. This site explores how the Capitol expanded at the very time our country was splitting apart and the legislative efforts that sought to mend our fractured nation. As Abraham Lincoln said about the construction of the Capitol's iconic dome, “If people see the Capitol going on, it is a sign we intend the Union shall go on.”
