Chicago, IL (AP) – Former President Barack Obama’s influence in his presidential museum runs deep, from the location on Chicago’s South Side to textured stone adorning its dramatic tower to striped reading chairs that resemble ones in his own home.

The Obama Presidential Center opens to the general public on Juneteenth after a celebratory dedication in Chicago with dignitaries. But tens of thousands of people — friends and family of museum staff, students and journalists — have already been offered a sneak peek of the nearly 20-acre campus as crews finish final art installations and landscaping.

The roughly $850 million project covers the political and personal realms of the nation’s first Black president. Campaign memorabilia and presidential artifacts are displayed in the admission-based museum tower while public spaces of the sprawling campus feature other things important to Obama: a new library, basketball court and picnic area with grills.

“This is a safe space for people to come and, yes, reflect on the historic moments of this presidency and the campaigns, but also to come together as a community to think about what change you can bring to your own neighborhood,” Josh Harris, the Obama Foundation’s vice president of public engagement, said during a recent tour with The Associated Press.

Here’s a closer look at the top attractions of the campus that is expected to draw as many as 1 million visitors annually.

President for a day

Obama’s presidential museum will be the first fully digital museum of its kind. There will be no official papers on display. Instead, visitors will experience high-tech and hands-on exhibits spanning the campaigns, key moments of Obama’s presidency and life at the White House.

One of the largest attractions is a life-sized replica of the Oval Office.

On a recent day, a stream of visitors, including schoolchildren, walked through the circular room, stopping to sit behind the desk and pose for pictures. The top drawer holds a copy of a handwritten letter from his predecessor, President George W. Bush, and Obama’s beloved BlackBerry phone.

“We want to make sure that people from all walks of life have the opportunity sit behind the Resolute Desk,” said Harris. “You think about the possibilities that if a young organizer from the South Side of Chicago can be president, you can be president too.”

Other sections of the museum detail the Affordable Care Act, immigration policies, and smaller moments such as when Obama unexpectedly sang during a 2015 eulogy for those killed in a South Carolina church shooting. A large television screen plays a clip of Obama singing “Amazing Grace.”

Peppered throughout are areas for personal reflection, which museum organizers say is key.

“We’re passing that baton and inviting people to bring change home, however change may be defined, both small or large,” said Louise Bernard, the museum’s director.

Touching iconic ballgowns

When Obama touted the museum’s contents at its groundbreaking in 2021, he predicted one of the top draws.

“We want this center to be more than a static museum or a source of archival research,” Obama joked at the site. “It won’t just be a collection of campaign memorabilia or Michelle’s ballgowns, although I know everybody will come see those.”

Roughly a dozen outfits on mannequins are behind glass, including a black and red dress designed by Narciso Rodriguez that the former first lady wore on Election Night in 2008 in Chicago.

Visitors will also get a chance to touch swatches of the fabrics, including the rose gold chain mail Atelier Versace evening gown she wore at her final state dinner in 2016.

Obama’s personal touches

The museum’s location is near where Barack Obama started his political career, taught law at the University of Chicago and where the family lived. Michelle Obama also grew up on the South Side.

A lifelong basketball lover, Obama requested a glass-paneled, professional grade basketball court to be used for community programs.

The former first lady designed a garden, where lettuce and strawberry plants are sprouting. There are also charcoal grills available for public use — an element that Obama envisioned when he pitched the plan in community meetings nearly a decade ago.

“President Obama always talked about his feelings of being in Chicago and one of his memorable moments was grilling in the park,” Harris said.

The Obamas’ design tastes and love of history are also evident.

The museum campus features dozens of commissioned works of art while different parts of the campus are named after prominent figures. The central “John Lewis Plaza,” named for the late congressman and Civil Rights leader, is designed as a public gathering spot.

Inside a new Chicago Public Library branch, a 70-foot (21-meter) mural depicts literary figures, including Walt Whitman and James Baldwin. At the center, Toni Morrison reads to a boy wearing orange shirt, representing a young Obama.

The presidential reading room features thousands of books chosen by the Obamas, ranging from presidential biographies to best-selling fiction. One of Obama’s favorite parts are two high-backed chairs with blue, yellow and black stripes. They were selected by the former president as top-notch reading chairs similar to ones he has at home.

Pricey admission with free options

Tickets are $30, the highest of any U.S. presidential museum or library. Next on the list is the Richard Nixon Presidential Library and Museum in California, where tickets are $29.

Obama Foundation leaders say the prices are justified for the state-of-the-art facility.

Tickets at the adjacent Griffin Museum of Science and Industry are $25.95. In downstate Illinois, tickets to the Abraham Lincoln Presidential Library and Museum in Springfield cost $15.

Along with free days and discounts for Illinois residents, Obama Foundation officials also argue that most of the campus is free, with only four floors of the museum tower requiring tickets.

Anyone can walk the campus, use the playground, library, sledding hill or grilling area. The tower’s top floor, which feature panoramic views of the nation’s third-largest city, is also free.

“The idea behind this institution, this campus, was to make it accessible to as many people as possible,” Harris said.
