The DC History Center occupies the enormous building at the center of Mount Vernon Square and has a research library and exhibit on D.C. history open to the public. The building was constructed in 1903 with funding purely from Andrew Carnegie's philanthropy as the second headquarters of the D.C. Public Library. It also houses an Apple store.
Its most popular exhibit is the Hall of Presidents. The enclosed Kogod Courtyard has received several architectural accolades. It has a small cafe and is a peaceful, quiet place to escape for a break. Free WiFi.
In the Pension Building, the building itself is highly recommended for its architecture, with an expansive open interior space with massive columns. The space is used on occasion for special events, including 10 Presidential inaugural balls. There is a small cafe inside, to the right of the entrance, and places to sit and relax, as well as a gift shop. The museum features long-term exhibits on the planning and building of Washington, D.C., and on green building and communities, along with various short-term exhibits and special events.
The collection here is a walk through encyclopedia of American Art—Gilbert Stuart's stern presidential portraits through Nam June Paik's house-sized America sculpture of neon and televisions.
Koshland is very much on the small side for D.C. museums, but it's great for kids, and for those happy adults who can let loose and act like kids.
