The Carnegie Library in Washington, D.C.
Like the Braddock Carnegie Library in Pennsylvania, this massive Beaux-Arts building located in Mount Vernon Square in Washington, D.C., is on the National Register of Historic Places. Funded in 1902 and designed by the New York firm of Ackerman & Ross, the structure is no longer only a Carnegie library; today it also houses the Historical Society of Washington, D.C., which includes the Kiplinger Research Library.
Recently, Apple proposed opening a flagship store in the historic building and reportedly is discussing a lease with Events DC, the authority that owns the property.
This Carnegie library was the first public library in the nation's capital, but it was important for another reason: It was D.C.'s first desegregated public building. While laws in the early 20th century mandated segregation in public schools and recreation facilities, no such requirement was in place for public libraries.
