Bologna's historic Garisenda tower undergoes safety assessment

The streets around the leaning twin towers of Garisenda in Italy's Bologna have been closed off due to concerns over the structure's stability. The 12th-century tower leans at an angle of four degrees and has been compared to the Leaning Tower of Pisa. Local authorities have installed sensors and pendulums to monitor the tower for any signs of movement or stress-induced noise. The closure of the roads has prompted political discussions about the tower's safety.
