On February 15, 2016, Presidents' Day, Rubenstein presented a gift of $18.5 million to the National Park Foundation to expand educational resources, foster public access, and repair and restore the Lincoln Memorial on the National Mall in Washington, DC. The Park Service plans to create 15,000 square feet of visitor space in the undercroft of the memorial. This gift, presented during National Park Service's centennial year, was Rubenstein's fourth gift to benefit US national parks. On December 2, 2016, Rubenstein in conjunction with the National Parks Foundation, agreed to cover the cost of elevator upgrades to the Washington Monument. The monument reopened on September 19, 2019.
