Built in the late 1960s at a time when relations between East and West Berlin were at their lowest ebb, the 368m (1,207ft) Television Tower - its ball-on-spike shape visible all over the city - was intended as an assertion of communist dynamism and modernity. East Berlin authorities, however, were displeased to note a particular phenomenon: when the sun shines on the tower, reflections on the ball form the shape of a cross.
Berliners dubbed this stigmata 'the Pope's revenge'. Nevertheless, the authorities were proud enough of their tower to make it one of the central symbols of the East German capital, and today it is one of Berlin's most popular graphic images. Take an ear-popping trip in the lift to the observation platform at the top. The view is unbeatable by night or day. If heights make you hungry, take a twirl in the revolving restaurant, which offers an even better view.
