Spiral Stair in a Brick Tower

Looking down this tower turns an ordinary staircase into a coil of stone and iron. Daylight enters through narrow windows, catching the outer edges of worn treads. Brickwork stays visible in the shade, with mortar lines bending around the cylindrical wall rather than running straight across it.

There is no single horizontal line to build around here. Instead, trace a short stretch of handrail and watch how its curve tightens toward the central opening. Steps nearest the viewer have broad pale surfaces; lower ones compress into thinner wedges. Keeping those sizes apart makes more sense than putting every gray piece in the same pile.
