Vieux-Lyon, Immeuble 10 rue Lainerie

In the courtyard, you can admire a staircase whose structure is remarkable, it is also a historical monument. Stand at the foot of the stairs and look up towards the top. Spiral staircases, such as this one, are amongst the plus audacious and are often called stairs without a core. This technique was outstanding until the sixteenth century as it required specific skills of the stonemason who carved the shaft, the step, the riser and the joint in one block of stone which then joined with the upper and lower steps to create the full spiral. Do not miss another specificity: the banisters are cut directly into the wall and the centre.
