Washington had a very different look during the Civil War, some 150 years ago now. As historians mark the beginning of the conflict’s sesquicentennial on April 12, we look for traces of Washington’s Civil War history, some of which is hiding in plain sight.

Quiz yourself to see how well you know your Civil War statues: For example, Which former Union general and U.S. secretary of war gives his name to a park in Foggy Bottom? Then, when you’re through being stumped, check out photos of the landmarks or upload your own photos as you encounter them around town.

Here’s the rest of what you’ll find in today’s Weekend section:

• Whether the government shuts down or not, you need to know what’s happening this weekend. Here are our top picks for the days ahead, including performances by the New York City Ballet, the Kronos Quartet, ‘SNL’ alum Tim Meadows and the debut of FilmfestDC. You’ll want to keep an eye on anything cherry blossom or Smithsonian related, however: Some of those events are subject to furlough. (UPDATE: The National Cherry Blossom Parade will take place regardless of a shutdown, according to the event’s organizers.)

•Even at 85, jazz legend Randy Weston’s output could tire a performer half his age. With a new album, “The Storyteller,” and a new book, “African Rhythms: The Authobiography of Randy Weston,” the pianist performs at the Kennedy Center Saturday.

•Yet another reason to like Fridays: Westend Bistro’s pop-up palace of BBQ.

•Explore weighty topics, including death, arson and lust at the...Renwick Craft Invitational?

•It made quite the splash when author Dave Eggers announced he was opening one of his 826 organization’s learning centers in D.C. And voila — it’s the Museum of Unnatural History!

•Vanguard British director Peter Brook returns to the Kennedy Center for the first time since 1973 with “Fragments.”
