Spiral staircases in medieval castles ascended clockwise to give defenders a combat advantage, making right-hand blows easier for defenders and harder for attackers.
The claims about spiral staircases in medieval castles being designed to ascend clockwise for defender advantage are supported by historical analysis. Evidence shows they were often designed this way, although around 30% did not follow this pattern. The idea is rooted in military strategy to favor right-handed defenders and hinder attackers with reduced weapon maneuverability. Claims about combat dynamics, including the effectiveness of right-hand blows and their limitations in stairwell combat, are plausible and generally consistent with martial arts principles. However, these assertive dynamics were strategic rather than consistently implemented across all castles. Overall, the claims are primarily supported with a few noted exceptions.

Evidence SummaryMultiple web sources suggest most medieval spiral staircases ascended clockwise, with some exceptions.
The hardest blow with the right hand in combat is from right to left.
There is limited evidence directly confirming this claim. Right-hand blows are indeed powerful in combat sports, but specific angles are less frequently documented.
