Library of Congress

Originally intended as a small reference library, the Library of Congress is now home to the second-largest collection of books and reading materials in the world, second only to the British Library. The collection comprises close to 100 million items, including rare documents such as the Gutenberg Bible, early drafts of the Declaration of Independence, and Lincoln's Gettysburg Address. The splendor of the magnificent Main Reading Room is just one of the attractions worth a visit at the Library of Congress. Browse through the many excellent exhibits on display in the library's three buildings, participate in a guided tour, or attend any of the concerts, lectures, and other events hosted here. The library's collection is open to all who hold a valid Reader Identification Card; however, materials cannot be taken outside the library premises. Other than the mind-blowing collection on display, the interiors of this centuries-old building are equally mesmerizing. Huge, vaulted ceilings with classic frescoes and designs, ivory pillars of Greek design, and the irreplaceable heritage surrounding the place make it one of the most iconic locations in the country.
