Pisa
The Duomo and the Campanile
The Duomo, or cathedral, of Pisa was built on the silty outer flood plain of the Arno. Unstable ground caused the bell tower to tilt radically even during construction, to the extent that the uppermost floors had to be built on a slant toward to center of mass in an attempt to even out the tilting. Still more special engineering has been required to prevent the structure from collapsing over the centuries since.

Pisa is the centuries-old location of schools of medicine and other guild professions.































The Duomo
By the end of WW II, the campanile was leaning so far that the city feared it would collapse. Engineers stabilized it and were able to reduce the lean to a manageable amount.
