St. Mark’s Campanile collapsed in 1902. It was rebuilt and would be reopened in 1912. In the meantime, it was natural to turn an eye towards Italy’s famous leaning tower in Pisa and consider its destiny.
In more recent history, the Leaning Tower of Pisa, which leans because it was built on a soft foundation, had work done to make sure it doesn’t fall. The bells were remove to reduce weight, counterweights were added, and it was straightened very slightly. It is estimated that it will remain stable for 300 to 400 years.
It also may have some help from Pisa Pushers.
WILL THE LEANING TOWER FALL AS DID THE CAMPANILE? Only the Excellence of Its Masonry, Which Makes the Walls One Mass, Has Kept the Structure From Collapsing Long Ago. (PDF)
