We’ve all marveled at the beauty of Apple’s stores and the simplicity of its architectural design, but Apple has taken it to the next level with its historic renovation of the Carnegie Library on Mount Vernon Square in downtown Washington, D.C. Apple restored the Beaux-Arts style building that was home to D.C.’s Central Public Library. Originally funded by Andrew Carnegie and opened in 1903, the building has become a combination Apple store and public space. The library also features the new DC History Center, which includes the Kiplinger Research Library, three galleries and a museum store, all owned and operated by the 125-year-old Historical Society of Washington, D.C. This turns out to be a great marriage of business and philanthropy.
