Spiral stair at La Sagrada Familia II

Having taken the lift up one of the towers of the Passion Facade of Gaudi's La Sagrada Familia, we then walked slowly back down to ground level. To start with the stair winds around just inside the outer wall of the tower, but after a while a very long and very narrow spiral stair is all that is left; this image is taken looking straight up from the base.

Presumably this is what the incomplete spiral staircase shown earlier in my stream will look like once complete.
