Last month, the National Park Service announced an $18.5 million donation to repair the Lincoln Memorial and build in a number of upgrades. Businessman and philanthropist David M. Rubenstein made the gift, which will expand the small exhibit space, adding new displays, and provide for desperate repairs to the iconic building and statue.

“These improvements will hopefully enable more people to better understand and appreciate Abraham Lincoln’s remarkable leadership during one of the most trying periods in American history,” Rubenstein said in a statement.

Among the repairs needed are fixes to damaged marble and brick, conservation of the murals and another elevator to improve accessibility.

The small exhibit space, which measures just 750 square feet, will be expanded significantly, to around 15,000 square feet. There’s also a “special project” in the works that “will provide future visitors with a glimpse of the memorial’s foundational pillars, which anchor the memorial to the bedrock, and of the graffiti of the workers who built the monument in the early twentieth century,” according to a press release.
