Ever wonder why most staircases in medieval castles were built to be
extremely narrow and spiraling in a clockwise direction? Since
medieval castles were built mainly as fortifications, staircases were
designed to make it extremely difficult for enemy combatants to fight
their way up.
Since most soldiers were right-handed, they would need to round each
curve of the inner wall before attempting to strike, inevitably
exposing themselves in the process. The clockwise spiral staircase
also allowed the defenders to use the inner wall as a partial shield
and easily allow them to swing their weapon without being hindered by
the curvature of the outer wall.
The stairs were also intentionally poorly lit and built to be uneven,
making it even more difficult for the attackers to gain any sort of
balance or momentum during their fight up to capture the castle.
