Leaning Tower of Pisa, Italy(意大利比萨斜塔) |
The world-famous Leaning Tower of Pisa ranks second on this list. It is a bell tower of the Cathedral of the Italian city of Pisa, known for its unintended tilt to one side. The construction of the tower began in 1173. However, only five or six years later, the tower began to tilt to the southeast, caused by an inadequate ground foundation – basically one that proved too soft on one side. Upon its completion in 1372, the tower was only bowing down some 4.5 feet downwards. As time passed by, the angle of the 16,000-ton tower has become more precarious.
The Leaning Tower of Pisa in Italy, an architectural wonder, is popularly regarded as one of the most dangerous buildings in the world. Can you think of any other structures which seem to be in great peril? They were purposely and skillfully constructed at the riskiest of locations or sometimes just had their appearance altered to reflect a sense of danger and awe.
