The Campanile of St Mark's Square, a cornerstone of Venice's architectural heritage, experienced a catastrophic collapse due to factors including age and lack of maintenance. This incident occurred in July 1902 and involved the complete failure of this iconic bell tower, known for its orientation alongside the famous basilica and doge's palace. The Campanile stood for nearly a millennium, with its current iteration constructed in the early 20th century, raising expectations for its permanence. The collapse also led to the destruction of the loggetta, which adorned its base and served as an entrance to St Mark's Square.

Witnesses observed the sudden and alarming fall that sent debris flying, shocking the citizens and tourists alike. Fortunately, there were no fatalities reported; however, the incident incited significant concern regarding the structural integrity of similar historical buildings. Immediate investigations prompted further evaluations of Venice's architectural landmarks, especially those constructed during the medieval period. Following the collapse, public meetings were held to discuss the future of the Campanile, leading to a reconstruction plan that aimed to restore the beloved structure to its former glory.

The aftermath of the collapse saw a mixture of grief and renewal, as the city began to raise funds to rebuild the Campanile. The restoration featured meticulous attention to detail, adhering closely to the original design while ensuring the use of improved materials and methods. In 1908, the new Campanile was inaugurated and has since maintained its status as a symbol of Venice. This event underscored the importance of preserving historical architecture and highlighted the impacts of neglect on cultural heritage sites.
