It's an enormous complex, containing FDR's childhood home, a visitor center with exhibits, and the archives themselves, plus outdoor space for exploring. I couldn't possibly do justice to the whole place in a short blog post, but I did want to point out a few things.
First, a re-creation of FDR's Oval Office, which uses a timeless, simple, effective exhibit technique to share more information about the objects in the space. I never get tired of seeing this done, because I can't recall ever seeing it really flop. (I'm sure it's happened somewhere.)
Second, this inviting outdoor sculpture. I often find outdoor sculpture creepy, especially when the figures are sitting on benches, looking very obviously not-alive, but this works for me. I admit to a huge history crush on Eleanor Roosevelt, and the idea of sitting down to talk books and big ideas with her is enormously appealing - and that's just what this looks like.
