(How to Get There)

Updated September 2003

Library Security Maps & Floor Plans

The Madison building of the Library of Congress occupies the city block bounded on the West by First Street SE, on the East by Second street SE, to the North by Independence Avenue SE, and to the South by C street SE. The building is color-coded by corner; the Southwest corner is yellow, Southeast is Red, Northwest is Green, and the Northeast corner is Blue. The main entrance is on Independence Avenue between First Street and Second Street.

There is a snack bar on the Ground floor (G), in the Blue corner, and a cafeteria on the Sixth floor. To get to these: Go past the guard station, turn left towards the Blue corner, to the end of the corridor, and turn right. To your right is a stairway and to your left is an elevator bank. To get to the snack bar, take the stairway one flight down and go left. To get to the cafeteria, take the elevator to the sixth floor, go left (Blue to Red direction) halfway to the end of the corridor turn right, and the cafeteria entrance is just a bit further, on the left.

From National Airport

Via Subway: the "Metro"

Take the Yellow Line, transfer to blue or orange at L'enfant Plaza, to Capitol South. Alternatively, you could take the Blue Line at National (both Yellow and Blue run on the same track) all the way to Capitol South, and avoid transferring, but this will take much longer, as the Blue Line takes a circuitous route.

Via Taxi

A taxi should take no more than 20 minutes, even in rush hour. Tell the driver "Library of Congress Madison Building, Independence Avenue between First and Second, Southeast". If he doesn't understand, get a different cab. According to, fare should be about $9.

Other Airports

National is by far the most convenient (and most pleasant) but if you have to fly to Dulles or BWI, see: Washington DC Airports

Subway Exits

Exit Union Station (Red Line) if coming from points northeast of Union Station along the Red Line, for example, Catholic U. in DC; or Takoma Park, Silver Spring, or Wheaton, in Maryland.

If coming from northeast along the Red Line, but the weather is bad, or if you don't want a long walk, then exit at Capitol South station on the blue/orange line (transfer at Metro Center station). Capitol South is much closer. (From Union Station, though, walking is quicker than riding to Capitol South.)

If coming from elsewhere (west DC, or from Virginia, or western part of red line in Maryland for example Rockville or Shady Grove), exit at Capitol South. (From Red line transfer to Blue/Orange at Metro Center.)

From Capitol South Station

Off the escalator, continue in the same direction to the street corner (at southwest corner of 1st and C intersection), continue one block further, to Independence Avenue, cross 1st Street (to the right), walk halfway to the next block, turn right, and you're at the main entrance.

From Union Station

Exit Union station from the main entrance (or Metro exit), facing Massachusetts Avenue to the South. Walk in a South to Southeast bearing and soon you will see the dome of the Capitol. Walk past (and to the east of) the Capitol to First Street. Walk along First Street, South (and depending on where you hit First street, you may pass the Supreme Court and the Library of Congress Jefferson Building, on the East side of First street), to (and across) Independence Ave. and there's the Madison Building

Via Car

Not a good idea.
