TO CALDWELL HALL

FREE PARKING for Caldwell Hall can be found in McMahon Parking Lot, located north of McMahon and between Caldwell and the Pryzbyla Center.

FROM THE BROOKLAND-CUA METRO STATION

Upon exiting the train, proceed down the escalators, and exit the station to your left, towards CUA.
At the top of the escalators/stairs, walk straight, following the path, until you come to a crosswalk. Across the street will be a guardhouse, next to a gated street that continues uphill onto campus.
Cross the street and continue past the guardhouse, walking uphill onto campus. You will pass Gowan Hall, then McCort-Ward Biology Building on your left, and Pangborn Building on your right (across the street).
At the end of the block, a parking lot will be on your left, and a crosswalk to your right. Cross the street, and turn left, continuing up the hill. You will pass Crough Center on your right, with a small grove of trees in front.
At the next intersection, there will be a row of hedges on your right, lining a side street that continues uphill to your right. Turn right and follow that street. Stay on that sidewalk as you bear left, then turn right onto another side street (a one-way street).
At the end of the block is a parking lot to your left. Cross the parking lot to the building on the other side - Caldwell Hall.
The entrance to Caldwell Hall is at the main entrance to the parking lot, by the circle. The ballroom is immediately to your right once you enter the building.
