WASHINGTON (Reuters) - Martin Luther King Jr stood 30 feet (9 meters) tall as a memorial to him was unveiled on Monday, the first on the National Mall in the nations capital not dedicated to a war, president or white man. Fifteen years after a Congressional Joint Resolution in 1996 to establish a memorial to honour King, the four-acre site on the Tidal Basin between the Lincoln and Jefferson Memorials opened to the public for the first time. From a geometrical standpoint its on a direct line between the Lincoln Memorial and Jefferson Memorial, said Bill Line, spokesman for the National Park Service. Visitors will walk through two massive white granite halves of the Mountain of Despair to reach the Stone of Hope, from which the sculpture of King emerges. The winning design from an international contest was inspired by the line from Kings I Have a Dream speech, Out of the mountain of despair, a stone of hope. Behind Kings sculpture, on either side of the mountain, is a 450-foot-long (137 metre) wall inscribed with 14 quotations from the famous orators speeches, sermons, and writings. His arms are folded, with one hand holding his rolled-up Dream speech, according to sculptor Master Lei Yixin, who is a Chinese citizen. Dr. Kings vision is still living, in our minds; we still miss him, we still need him, said Yixin through a translator, who described the sculpture the most important of his life.
