The SIS Building from across the River Thames, London. Designed by architect Terry Farrell, this building has been the headquarters of MI6 since its completion in 1994. It has been nicknamed 'Babylon-on-Thames' because of its perceived resemblance to a Babylonian ziggurat. Vauxhall Bridge is on the right. (Photo by Peter Thompson/Heritage Images/Getty Images)
