center of the castle is called the Inner ward,
which is the inner curtain or the innerpart of the wall.
The barracks are off to the right of the
inner ward. The barracks are where the knights stay. The stables
are below the barracks.
From the 13th century, castles were usualy built with rings
of stone, one inside the other. These are called concentric
The outer wall was pretty close to and a
little lower than the inner wall. Sometimes the outer wall
was so low that it seemed no more than a wall of protection
against attacking machines, such as catapults.
But it meant that archers on the inner walls could shoot over
the heads of those on the outer, bringing more fire power
on an enemy.
If attackers broke through the outer wall, they would still
be faced with the inner wall.
In older castles the great tower and curtain wall
were sometimes given an outer ring of walls, making three
lines of defense.
