The John F. Kennedy Eternal Flame is a presidential memorial at the gravesite of assassinated United States President John F. Kennedy, in Arlington National Cemetery in Virginia. This permanent site replaced a temporary grave and eternal flame used at the time of President Kennedy's state funeral on November 25, 1963, three days after his assassination. The site was designed by architect John Carl Warnecke, a long-time friend of the president. The permanent John F. Kennedy Eternal Flame grave site was consecrated and opened to the public on March 15, 1967.
