       | I would have argued the contrary, the vast majority of European
       | castles were uninhabited or manned by a skeleton crew the
       | majority of the time, and only inhabited when threats demanded
       | it.
       | 
       | There certainly were castles that served as primary residences
       | (like the mentioned Arundel Castle), but this mostly became the
       | fashion after the medieval time, when the transition from the
       | fortified castle to the beautiful and nice-to-live in chateaus
       | happened, with fortification elements that were more symbolic
       | than practical (English lacks a clear distinction in name here,
       | but at least German and French draw a clear line here).

       | 
       | You can see hundreds of architectural decisions that were made
       | with military aims -- some of them didn't work, and some of them
       | weren't used.
       | 
       | But, whether staircases were made with the righthanded swordsman
       | in mind is irrelevant. They _were_ created with right-handedness
       | in mind. Because of the placement of railings.

       | make the first step with your right foot and use your dominant

         | house (and staircases) design.
         | 
         | There are some geometrical limits that will make the stair
         | start and land on the same or opposite side, both "top" vs.
         | "bottom" and "left" vs. "right".
         | 
         | Usually (but not always) you want the stair to start and land
         | on the same (bottom vs. top) side and this - generally speaking
         | - implies having a 180deg turning of the stair, which itself
         | implies that if you start left, you land right or - viceversa -
         | if you start right you land left.
         | 
         | How much is the height you have to cover?
         | 
         | How large is the staircase diameter?
         | 
         | A typical height of around 3 meters will give you, with steps
         | between 15 (very "plain") and 25 cm (rather steep) anything
         | between 4 and 5 (max 6) steps per meter of height.
         | 
         | If you have a 2 m diameter staircase and a central hub of - say
         | - 40 cm diameter, each step will be 80 cm wide.
         | 
         | On the outer side it will be anything between 25 and 35 cm.
         | 
         | So, let's test what happens with 15 cm high steps and outer
         | side 30 cm.
         | 
         | The perimeter of the staircase is Pix2.00=6.28, with 30 cm on
         | the outside it will give you around 6.28/0.30=~21 steps for a
         | 360deg rotation, and 21x15=3.15 height, but you want actually
         | 180deg or 540deg as you would want to have the stair land on
         | the same side (top vs. bottom), for 180deg you have only 10/11
         | steps, and you cannot make 27/30 cm high steps.
         | 
         | So you either enlarge the staircase (to increment its
         | perimeter) or reduce the max size of the step (but remember
         | that when you decrease the size of the step on the outer size,
         | the size near the hub will also become smaller).
         | 
         | Let's try again with the same 2 m diameter staircase and 25 cm
         | outer step, 180deg 3.14/0.25=12,56->13 steps 3.00/13=0.23 cm,
         | steep but doable.
         | 
         | In a "lower left corner" (what you can imagine as a letter "L")
         | it makes sense (to minimize area needed) to have the first
         | step, at the lower level, on the left (but you will land on the
         | right).
         | 
         | In practice you have to decide whether you want around 1 meter
         | space between the outer (left) wall and the step on either the
         | lower or the higher level, it depends, but you want the extra 1
         | m space at the level where you can possibly put some piece of
         | furniture (a closet, a library, whatever).
         | 
         | There is no particular ergonomical reason (AFAIK) why one would
         | prefere a clockwise or anticlockwise staircase, as you noted if
         | one might feel more comfortable going up, it will feel less so
         | going down or viceversa.

       | 1. "Castles were built for prestige not fortification".
       | 
       | Regardless of actual use as fortification (frequency of battles),
       | it's pretty self-evident that the intent of much of a castles
       | design is fortification. Even if moats, arrow slits and parapets

       | defensive capabilities_ , in which case (at least apparent)

       | 2. "Some turn anti-clockwise"

       | Wherein the author assumes that all wisdom is automatically

       | 4. An argument against how practical they would be in reality

         | 2. What author meant was that 30% of them who were anti-

         | projected by people who thought of using stairs as battle
         | scene.
         | 
         | 3. I've mostly visited early medieval castles, that had anti-
         | clockwise stairs, so meh... it looks like a cultural thing. I
         | even doubt that these were used when carrying sword, because
         | those had not much space to have it there, so it looked like
         | something to be used for practical everyday usage - not
         | battles.
         | 
         | 4. If a person was wearing armor in medieval times, he was like
         | a tank. If there was a discussion among nobles and one of them
         | got pissed and decided to wear an armor and return to continue
         | discussion... well, pretty much the discussion was over for
         | rest of party, regardless of presence of swords. Though,
         | despite the trope used in cinema, I can't imagine swordfighting
         | in medieval setting between armored opponents on stairs. If the
         | one on top of stairs slipped, the opponent below would be
         | disabled from the weight of opponent above him. They would also
         | not be able to step on those stairs... and if it all comes to
         | that, swordfight is not requirement to rat out enemy - for that
         | was used fire and smoke. Pretty much it is what author was
         | mentioning - if there is a breach, it is game over for
         | defenders and no real reason to continue defending anymore. The
         | only thing they can try is fleeing.
         | 
         | Fighting, that involves swords and no armor is very late

       | If the newel post is on the same side as their sword then when

       | their sword (unless they can lean far enough over to attack

             | A few hypotheses come to mind:
             | 
             | 1. Walking on your toes vs. on your heels
             | 
             | 2. What happens if you slip

             | 3. Lean
             | 
             | If you're facing into the stairs, your toes are gripping
             | the next step. Maybe the extra degree of freedom from your
             | ankle makes it easier to get a steady foothold. Whereas if
             | you're facing away, on narrow steps, your toe may be off
             | the step. If you try to balance on level ground on the
             | balls of your feet vs. on your heels, you can tell heels
             | are harder.
             | 
             | If you're going up and you slip, your moving foot just
             | slides onto the same step as your static foot. If you're
             | going down and you slip, your feet are now separated by 2
             | steps instead of just 1.
             | 
             | All things that move across ground move best if they lean
             | into the direction they're walking. If you're walking down
             | stairs, leaning forward means leaning away from the stairs.
             | Going up, you're just leaning into the stairs as if you're
             | rock climbing. Also it's likely our bodies are just better
             | at leaning forward safely than backwards.

         | 
         | Incidentally, if you're not aware of it, a 1 inch difference in

         | 
         | Also the notion that once attackers were in a castle it's all
         | over is not true. Late medieval castles were designed to be
         | modular, layered and flexibly defensible. The enemy might get

         | that. Might give you enough time to be relieved by an external
