The Martin Luther King Jr. Memorial Library is the only building in Washington DC designed by Ludwig Mies van der Rohe. Designed in 1972, it was his last piece of work before he died at the age of 83 without ever seeing its complete construction. The 400,000 square foot public library is the central facility of the district’s library system but it has been plagued by mechanical failures for many years. Mayor Anthony D. Williams and the library board wanted to replace the aged facility with a new building but the DC historic preservationist board sucesfully added the building to the National Record of Historic Places, effectively preventing immediate demolition. There are tentative plans for renovation, including painting the dark steel facade silver, replacing the tinted glass with clear, and adding an additional floor with roof terrace (an option designed into the original structural frame).
Notice the famous Barcelona Chairs, originally designed by Meis in 1929.
