Unlike its taller neighbour, nan Garisenda Tower has been astatine consequence of illness almost from nan infinitesimal building was completed.

Similar to astir of Bologna's medieval towers, nan Garisenda Tower was built connected a ring-shaped guidelines of mortar terracotta bricks, and stream stones.
It is this guidelines worldly which is nan apt origin of nan tower's drastic thin arsenic nan instauration sinks into Bologna's soft ground.
Nunziante Squeglia, an master astatine nan University of Pisa says that some Pisa and Bologna stock a akin problem pinch mediocre crushed conditions for construction.
'Like Pisa, Bologna is built connected a plain, and location is simply a problem pinch soft clay earth,' Mr Squeglia told nan Times.
The properties of this soft clay, mixed pinch nan mediocre building of nan tower's instauration person caused Garisenda to simply descend into nan world and database to 1 side.
Others blasted nan metropolis council's determination to let postulation astir nan guidelines of nan tower, claiming that vibrations from passing vehicles whitethorn person further destabilized nan foundations.
Raffaele Milani, nan Bologna caput of Italian practice group Italia Nostra, told nan Times: 'We person been saying nan area should beryllium pedestrianised for years.'
