Due to the ongoing COVID-19 pandemic, NALC Headquarters is currently closed to the public. For more information, or if you have any questions, please call 202-393-4695.
The Vincent R. Sombrotto NALC Headquarters building sits in a prominent location at the foot of Capitol Hill. When NALC purchased the site, it was one of the last available for development adjacent to the U.S. Capitol grounds.
Another unique feature of the Headquarters building is its outer shell, made of unpolished, high-quality Vermont marble. There are only a few other buildings in Washington, DC, with marble from the same quarry—including the U.S. Supreme Court building and the Jefferson Memorial—making the NALC building architecturally significant.
Tours of the Sombrotto Building given by NALC employees are available for visiting members between the hours of 9 a.m. and 4 p.m. No appointment is necessary for a tour—simply request one at the guard’s desk on the first floor of the building. Friends and family are also welcome to come along with a member during a tour.
Our street address is 100 Indiana Avenue, NW, Washington, DC 20001-2144, but taxis are best directed to “First and ‘C’ Northwest.” There is a taxi stand around the corner from the Sombrotto Building, on Constitution Avenue at Charlie Palmer Restaurant.
Union Station is an easy, 20-minute walk to and from NALC Headquarters, under a mile away. Amtrak, MARC Rail and VRE serve Union Station, and popular bus lines such as Greyhound and Bolt Bus have terminals inside Union Station’s parking garage.
The nearest Metrobus stops are served by routes X1, 96 and 97.
The nearest Metrorail stations are on the Red Line—Judiciary Square and Union Station.
There is a Capital Bikeshare station around the corner at Constitution Avenue & 2nd Street NW, in front of the Department of Labor building.
