After more than a decade of planning and legal challenges, the Obama Presidential Center officially opened Thursday on Chicago’s South Side, marked by a high-profile ceremony featuring four former U.S. presidents. The event drew Barack Obama, George W. Bush, Bill Clinton, and current President Joseph R. Biden Jr. to the stage, while former President Donald Trump was not invited, following his recent critical remarks about the center.

The opening celebration included musical performances by The Roots, Christina Aguilera, and Bruce Springsteen. In his remarks, Obama reflected on his arrival in Chicago over 40 years ago and emphasized the center’s dedication not only to his presidency but also to the broader values of democracy. “I hope this center will serve as an affirmation of just how special, how precious, our democracy truly is,” he said.

Michelle Obama highlighted the contrast between the Obama administration’s achievements and recent political tensions without explicitly mentioning Trump. She praised her husband’s efforts to revive the economy, expand health care, and provide comfort during national tragedies, noting that he persevered amidst attacks on his legitimacy and patriotism. “You did it all with such grace and class and cool that you made the hardest job in the world look like a walk in this beautiful park,” she stated, as Obama appeared visibly moved.

The $850 million, 19-acre museum campus sits in Jackson Park near the University of Chicago and includes community amenities such as a playground, public library, and sledding hill. President Obama announced plans for the center in 2015. The Obama Foundation, which financed the project through private donations, plans for the site to employ 250 people and attract about one million visitors annually. Adult tickets are priced at $30, with a discounted rate of $26 for Illinois residents.

On the morning of the opening, many Chicago residents gathered on the Midway Plaisance, nearby, to watch the event on a large screen. Among the invited guests at the museum were former Vice President Kamala Harris, House Speaker Nancy Pelosi, California Governor Gavin Newsom, foreign dignitaries, and numerous local figures. Several attendees, including comedian Stephen Colbert and Obama Foundation board chair Martin Nesbitt, wore tan suits as a nod to Obama.

Illinois Representative Mike Quigley, a Democrat who recalled a breakfast with Obama following his initial congressional defeat over 25 years ago, expressed amazement at the center’s completion. Actor and rapper LL Cool J described the museum as a source of inspiration, particularly for young people. Former White House Chief of Staff and Chicago Mayor Rahm Emanuel, who helped bring the center to the city, called it “a billion-dollar infusion of an investment that pays dividends way beyond the billion dollars,” particularly benefiting the South Side.

The Obamas have emphasized that the facility is not intended as a traditional presidential library but as a community hub featuring gardens, a basketball court, and performance spaces. Official presidential records will be maintained separately by the National Archives.

Located on the shores of Lake Michigan in Jackson Park near the Woodlawn and South Shore neighborhoods, the center sits in an area affected by frequent gun violence. In April, a 16-year-old boy was fatally shot two blocks from the museum site. Local residents voiced mixed reactions to the center’s arrival—hope for economic development tempered by concerns over potential gentrification and rising housing costs.
