As the Barack Obama Presidential Center takes shape ahead of its June 2026 opening, some observers have pointed feedback about an element of the building’s design.

The Chicago tower features all-caps lettering that wraps around two sides of the building. But for many people, the text—an excerpt from the former president’s speech in 2015, on the 50th anniversary of the marches from Selma to Montgomery, Alabama—is nearly impossible to read.

Its designers say legibility isn’t the only—or even the primary—function of the lettering.

“One of the key questions I asked at the beginning was, are people supposed to read this?” says designer Micheal Bierut, who typeset the lettering with a team at Pentagram, led by designer Britt Cobb. “Is legibility the primary goal here? Do we want people to be able to stand on the ground, look up at this tower, and read those words? And that was discussed on the client end, and the answer came back, ‘No, it should have the promise of meaning, it should be decipherable, everything should be spelled right and it should make sense.’”

Letters as texture

Early concepts of the Obama Presidential Center designed by Tod Williams Billie Tsien Architects (TWBTA) showed a perforated upper section depicted in drawings as an abstract, irregular pattern. At one point, architects considered filling the space with a bunch of words, like a word cloud, though that idea didn’t feel quite dignified enough for a presidential library. Instead, they decided to use an excerpt from one of Obama’s speeches.

“Just as a million people go to the Lincoln Memorial, some of them will stand and read every word of the second inaugural; some people will just admire the statue in the building and kind of take it in, and a couple of words will jump out, but not the whole thing,” Bierut tells Fast Company. “It’s in that tradition that I think we were operating.”

The function of the feature is to serve as a space on the building that would be illuminated to the outside at night; from the inside, it’s a viewing area. Bierut says it was “never intended to look or feel or communicate as an applied sign stuck on the building.” It’s part of the architecture, not separate from it.
