Perhaps the best known is the Leaning Tower of Pisa. Soil settling unevenly caused the tower to tilt- a LOT!
Leaning Tower of Pisa
It's a building, a Tower. Originally intended as a bell Tower for a nearby Church. It's leaning b/c it was built on unstable soil.
because its soil was built unstable
There are no rooms in the tower. It is a bell tower built in 1173 and on sandy soil. Before it was finished it was leaning.200050000
The Leaning Tower of Pisa has a bronze door, as well as column with Corinthian capitals. It leans because it is built on unstable soil.
The Tower does not grow 2 m each year. If anything, it's more likely to sink/shrink, since its built on unstable soil.
The Leaning Tower of Pisa is important because it is an example of medieval Italian architecture. It is a UNESCO World Heritage Site.Because it was built a VERY long time ago and was built on unstable soil and now leans. A lot.Because it's on a lean (:
The Leaning Tower of Pisa's foundation was built on unstable soil so when they had finished the third floor it started to lean to the south. I think that the builders were humiliated at first.
Clay
Because when they built the tower after the third floor, they tried to correct the inclination to keep the center of weight well inside the basement. The result is that the tower is slightly banana-shaped. We can appreciate the different inclination in particular on the last floor. If the tower was straightened completely, the center of weight will cause the tower to fall on the opposite side.
That's all down to how the soil was deposited there, back in the Days. old river beds, sea bottoms. Places like that can have quite loose soil.
The Leaning Tower of Pisa wasn't invented it was built as a bell tower for the church it stands next to in Pisa. It was built in 1173. The church is the work of Giovanni and Nicola Pisano, but nothing lists the Tower's maker. I would assume it is the men listed above.
