D.C.'s Premier Event Spaces
The building's stylish spaces create an extraordinary experience for all types of events.
Located in Chinatown/Penn Quarter, The National Union Building is an elegant, historic building encompassing 6 floors of dedicated event space.
Designed by local architect Glenn Brown and built in 1890, the National Union Building boasts a striking Romanesque, stone clad façade and maintains captivating period details that give it character unlike anything else in D.C.
Soaring ceilings, curved glass, and exposed brick greet guests as they ascend our original wrought-iron staircase or the city’s last remaining central-core elevator cage.

Alberto is the best catering manager ever!! Everything about working with Catering by Season, from the planning, communication, to the execution was phenomenal!
I can’t say enough great things about our entire experience planning our daughter's Bat Mitzvah with Glynis Keith, Catering Manager, with Catering by Seasons.
Catering By Seasons exceeded my expectation. I used them for a brunch at my house after my son’s bar mitzvah. The level of professionalism along with their responsiveness made me feel at ease right away.
