Classic Projects: Great Wall of China Find out how the Great
Wall of China was built You can't see it from space, but the
Great Wall of China is undoubtedly one of humankind's greatest
construction achievements. Contrary to popular opinion you can't
see it from space, but the Great Wall of China is undoubtedly
one of humankind's greatest construction achievements. According
to one set of statistics, if you were to use all of its bricks
to build a wall around the equator, the Great Wall of China
would still be a metre wide and two metres tall. This might be
an exaggeration, but there is little wonder that is has been
called one of the greatest civil engineering projects of all
time. In fact, the wall is several projects, spanning centuries
and millennia. Although it's virtually impossible to come up
with agreement over its unit cost, economists think that to
build something comparable today would cost £300bn. Others
compare it with the construction of the UK's road networks over
the past four decades. Whicheve
