Welcome to one of the world's biggest goof ups!
Can you imagine being the Architect on this job when it was completed in the late 1300's.
Well, Bonanno Pisano (architect's real name) noticed the leaning after completion of the first three tiers.
I can hear the discussion between the Bonanno and his work crew:
"Hey guys, the thing is leaning..."
"Bonanno, the soil is too soft.....but it should hold up"
Since then the Tower has become a world tourist attraction... who would have thought it.
The Tower was leaning too much in the last century and in 1998,
work was done to remove soil from the high side and let it lean back a bit.
The work succeeded and the Tower now has a lean of 4.1 meters.
