Less Is More: 10 Buildings by Ludwig Mies van der Rohe

As his last building and his only library, the Martin Luther King Jr. Memorial Library (MLKML) is the central facility of the District of Columbia Public Library System. The 400,000-square-foot steel, brick, and glass structure was completed in 1972 and is a rare example of modern architecture in Washington, D.C. Currently closed for updates, the building is scheduled to reopen in 2020.
