a small section (about 100 metres)
of the Berlin Wall is on display in Berlin. This section of wall is part of the
fourth-generation wall (aka Stützwandelement UL 12.11) which was built
between 1975 and 1980 and comprised 45,000 re-inforced concrete panels
3•6 metres (12 ft.) high and 1•2 metres (3ft. 9in.) wide with round pipe on top.
