The Lister Hill Center (Bldg 38A) is a 5-minute walk from the Medical Center stop on the Metro Red Line, but all registrants must first pass through the Visitor Center Gateway. To do so, walk straight from the top of the Metro escalator, past the bus stops, and enter the Visitor Center Gateway. If you drive, there is a visitor parking garage next to the Metro station.
At the Visitor Center Gateway, you must show a government photo ID. You will then be issued an identification badge which will also serve as your name tag for the symposium. More information on the Gateway Center and general visitor information can be found here.
After exiting the Gateway Center, turn left, walk down the ramp and turn left to walk up an asphalt path to a concrete sidewalk. You will go past the Natcher and the Child Care Center, and across a road. Along the way, there are signs directing you to the National Library of Medicine (Bldg 38) or the Lister Hill Center (Bldg 38A). Follow the signs for the Lister Hill Center.
