On July 14, 1902, the 323 foot St Mark's Campanile in Venice, Italy collapsed after its northern load-bearing wall began to separate from the main structure. The cause of the separation was attributed to over 700 years of wear on the structure, including fires, earthquakes, and stress-redistribution, primarily from drying-induced shrinkage on the wooden support beams, the bells themselves swaying back and forth, and creep. No one was injured except for a cat belonging to a caretaker. The tower was a stonemasonry design.
