 Assembled using only pegs, without nails or glue, the fastening of the stairs at the top is probably not for supporting any weight.  Instead, this giant wooden spring supports enormous weight with its coil rigidity.  While one physics analysis suggests that the maximum deflection in the stairs occurs on its middle step, it appears more likely to occur at its highest step (just prior to the loft).

 The '''Physics of Loretto staircase''' is how the [[Loretto spiral staircase]] is so incredibly sturdy and durable without any supporting column, easily handling far more weight on it than one would expect.
-Its spring-like quality suggests that it '''''functions more like a coil than an ordinary staircase'''''. Placing weight on its upper steps can have the effect of compressing the coil, which results in added resistance from the coil sufficient to support far more weight than expected. The elasticity of this coil structure dictates how much force it exerts in resistance to added weight on the upper steps.
