Ever since humans began to live together in settlements they have felt
the need to organize some kind of defense against potentially hostile
neighbors. Many of the earliest city states were built as walled towns,
and during the medieval era, stone castles were built both as symbols of
the defenders' strength and as protection against potential attack. The
advent of cannon prompted fortifications to become lower, denser, and
more complex, and the forts of the eighteenth and nineteenth centuries
could appear like snowflakes in their complexity and beautiful geometry.
Without forts, the history of America could have taken a very different
course, pirates could have sailed the seas unchecked, and Britain itself
could have been successfully invaded.
This book explains the history of human fortifications, and is
beautifully illustrated using photographs, plans, drawings, and maps to
explain why they were built, their various functions, and their immense
historical legacy in laying the foundations of empire.
