The John F. Kennedy Memorial Plaza is free and open 24 hours a day. A block from Dealey Plaza, the memorial is easily reached from Union Station or West End Station. Created by architect Phillip Johnson (a Kennedy family friend) and dedicated in 1970, the memorial is surrounded by large concrete walls that appear to be floating. The memorial itself is a slab of black granite simply inscribed with the late president's name. It's definitely worth a quick visit during the day or at night when lit by floodlights.
