The White Tower is the name of the central keep of the Tower of London, as built by William the Conqueror from 1077 onwards, 11 years after the Norman Conquest. Towards the end of the 11th century they added a wall round it. Under successive monarchs it expanded into the rambling complex we know today, but the White Tower - austere, cuboid - continues to stand alone on the north bank of the Thames, retaining its power as the very image of a fortress. A millennium later, it is to receive a 21st-century homage on the other side of town: the new American Embassy, by architects Kieran Timberlake.
