Library of Congress, Thomas Jefferson Building

Local nameLibrary of Congress, Thomas Jefferson Building
LocationWashington D.C., United States

Possibly the largest library in the world as well as the oldest cultural institution in the US. It is divided into three buildings. The most often visited one is the Beaux-Art Thomas Jefferson Building (the oldest one of the three, finished in 1897). All three buildings are connected by underground passages.

The library houses the largest collection of books and other materials (CDs, maps, photographs etc.) in North America and one of the largest ones in the world (growing every day). A significant amount of books of the Library of Congress is in languages other than English (almost 500 different languages).

There are free guided tours organised daily and a special family tour, suitable for small children, on Saturday. You do not need to book the tours in advance.
