Its ~5.5° tilt (reduced from 5.5° to ~3.9° after 1990s stabilization) creates a visual paradox—appearing to defy physics—making it instantly recognizable worldwide.
Despite the lean, the tower has stood since 1372. Centuries of soil extraction, counterweights, and ground anchoring preserved it—a testament to adaptive engineering.
