The Round Tower

The story

This plate from Le Carceri d'Invenzione stages a massive cylindrical tower wound with spiral stairways and cantilevered walkways, barred windows piercing the drum at irregular heights, the whole structure dissolving upward into a vaulted, half-lit ceiling with no visible source of light. Piranesi trained as an architect before he became a printmaker, and the Carceri series is where that training turns openly speculative — every stair, arch, and beam is drafted with real structural logic even as the overall space defies any coherent floor plan, a building that could never actually stand but reads, plate by plate, as if it could. What to notice: tiny human figures scattered across the stairways — barely more than a few etched lines each — exist purely to establish scale, and it is entirely through their smallness that the architecture around them reads as monumental rather than merely large.
