You have to make an effort to visit the Kreeger, because it’s located in a residential neighborhood away from downtown, the heart of Georgetown, and public transportation. But if you don’t mind driving, taking a taxi, or riding the D6 bus from Dupont Circle, then walking a half-mile up the hill to the museum, you’ll be well rewarded. On view throughout this unique building designed by Philip Johnson and Richard Foster, besides the stunning architecture itself, are paintings, sculptures, prints, and drawings by 19th- and 20th-century European artists, Picasso (early and late), Kandinsky, Monet, Renoir, Munch, Pissarro, and Rodin among them. American works are on view, too, including some by Washington, D.C., artists such as Sam Gilliam and Gene Davis. Downstairs lies a small collection of traditional African masks and figures and Asian pieces. Outdoors is a sculpture terrace, where large works by Maillol and Henry Moore, and the sight of the distant Washington Monument, are some of the pleasures at hand. Situated on a summit, this 5 1/2-acre estate opened to the public in 1994. At this writing, a timed entry pass was required to visit the collections inside.
