Washington D.C. Capitol & Library of Congress Tour - Underground Tunnels

Start at the Supreme Court
and explore Capitol Hill landmarks

The tour begins at the U.S. Supreme Court, also called the "Marble Palace" for its white marble, neoclassical design. Admire the building with your guide while hearing about the landmark cases that shaped American history. This 3-hour small-group tour guarantees entry to the U.S. Capitol and the Library of Congress.

Tour inside the Capitol with a docent

Enter the Capitol with your reserved ticket and join a docent-led tour. Admire the architecture as you explore the Crypt, the Rotunda and National Statuary Hall, and hear how the Capitol survived the Burning of Washington and how the Statue of Freedom was placed atop the dome during the Civil War.

Walk through hidden underground tunnels

Move between historic buildings around the Capitol through underground tunnels. Originally built to protect lawmakers and keep Congress running smoothly, the tunnels offer a fascinating behind-the-scenes look at how the government works.

Discover the treasures of the Library of Congress

The tour ends at the Library of Congress. Admire the ornate main hall decorated with mosaics and sculptures, and see treasures such as Thomas Jefferson's personal library, the Gutenberg Bible and Abraham Lincoln's draft of the Gettysburg Address. You can also see the rotating "Treasures" exhibition, featuring artifacts such as the handwritten lyrics of The Sound of Music, James Madison's crystal flute and Spider-Man comics drawn by Stan Lee and Steve Ditko.

The Library of Congress is closed on Mondays. Monday tours visit the United States Botanic Garden instead, with its glass-domed conservatory, rainforest and First Ladies Water Garden, and pass the Bartholdi Fountain, created by Bartholdi, the designer of the Statue of Liberty.
