International Affairs Building

Map to International Affairs Building


The International Affairs Building (IAB) is also often refered to as SIPA (because it houses the School of International and Public Affairs).   IAB can be accessed two ways:

The street-level entrance is located at 420 West 118th Street (between Amsterdam Avenue and Morningside Drive).  The entrance here grants access to the fourth floor.

To access the campus-level entrance, enter the main Columbia gates at 116th Street and Broadway, and walk up the steps of Low Library. Turn right (east) at the top of the first set of steps, and keep walking east until you come to Philosophy Hall. Turn left (north) at Philosophy Hall and walk until you see a ramp on your right going (east) over Amsterdam Avenue.  Take that ramp and walk straight ahead.  On your left, beyond the Casa Italiana, will be the campus-entrance to IAB.  The entrance grants access to the sixth floor.

Altschul Auditorium (417 IAB)

From the street-level entrance or nearby elevator bank on the fourth floor, walk up a short flight of steps toward the outdoor atrium.  Turn right at the atrium, and follow it around to the left.  Altschul Auditorium will be located at the end of this hallway.

1501 IAB (Kellogg Center)

To access 1501, take the elevators to the 15th floor.  Exit the elevators and walk north.  1501 will to your right.
